Abstract
Alloys which are resistant to erosion, particularly iron-based, cobalt-based and nickel-based alloys, contain a sufficient concentration of titanium carbide, typically from 5% to 60% by weight, to achieve the erosion-resistance required. The alloys also have preferred particle size ranges for the titanium carbide, the metal or alloy matrix and any other component, in order to exhibit the desired erosion resistance.
Description
SPECIFICATION
Erosion-resistant Alloys
The invention relates to hardfacing alloys generally and is particularly concerned with hardfacing alloys having enhanced resistance to erosive wear.
In the following description, all amounts given as percentages are by weight of the total of the alloy or alloy component as the case may be.
Manganese steel consisting of 12% manganese and 1% carbon, balance iron, is commonly employed when work-hardening is both permissible and desirable. Initially, manganese steel usually has a hardness of Rb88 to 92 which, after work-hardening, increases to Rc50 to 52.
Although manganese steel exhibits sufficient resistance to various kinds of wear, such as abrasive wear and adhesive wear including galling, it is lacing in resistance to erosive wear, particularly before it has been work-hardened. It has been found that even the well-known nickel-based hardfacing alloys are lacking in resistance to erosive wear.
In one test, a well-known nickel-based hardfacing alloy, consisting of 0.5% carbon, 2.2% boron, 13.5% chromium, 3.5% silicon and 2.8% iron, balance nickel, was deposited on a substrate of manganese steel by the plasma transferred arc process.In this test, Linde's Plasma Transferred Arc
System was employed at 200 amps and 30 volts, in order to deposit an overlay 3 mm (1/8 inch) thick of the hardfacing alloy on a piece of manganese steel measuring 50x50x25 mm (2 x2 x 1"). The resultant nickel-based hardfacing alloy surface was subjected to erosive wear, by impinging on it chilled cast iron grit at 4.2 Kg/cm2 (60 psig) for 4 minutes and comparing the weight loss from the erosive wear with that exhibited by a manganese steel control subjected to the same treatment.
Surprisingly, the nickel-based hardfacing alloy lost 4.5 grams, compared with a loss of only 2.8 grams by the manganese steel control.
It has now been discovered that nickel-based and other hardfacing alloys can be made which are much more resistant to erosive wear.
According to this invention, a hardfacing alloy comprises a metal or alloy matrix and titanium carbide in a concentration just sufficient to achieve the desired degree of erosive wear resistance.
In accordance with preferred features of the invention, the matrix is an iron-based alloy, a cobaltbased alloy or a nickel-based alloy.
Preferably, the titanium carbide is present in a concentration in the range from 5% to 60% by weight.
In accordance with an especially preferred embodiment of the present invention, the alloy consists of 10% to 25% of titanium carbide in a suitable matrix, preferably iron-based; such an alloy has notably enhanced erosion resistance and also exhibits low porosity and freedom from cracks, as is evidenced by the following tests.
Four test materials were employed.
Test material 1 was ordinary manganese steel plate comprising 12% manganese and 1% carbon, balance iron.
Test material 2 was an alloy comprising 1 5% titanium carbide, 7% nickel and 78% of an ironbased matrix comprising 29% chromium and 2.5% carbon, balance iron. This test material was applied to a substrate of manganese steel, measuring 50x50x25 mm (2x2"x1") by the plasma transferred arc method, as a deposit approximately 3 mm (1/8 inch) thick.
Test material 3 consisted of 50% tungsten carbide and 50% of a nickel-based matrix comprising 14% chromium, 3% boron and 4% silicon, balance nickel.
Test material 4 consisted of 20% titanium carbide, 7% nickel and 73% 316 stainless steel.
Test materials 3 and 4 were applied to manganese steel substrates in the same manner as test material 2.
The four kinds of test piece were subjected to a variety of treatments, including erosive wear, abrasive wear and hardness.
Erosive Wear Test
This consisted of impinging chilled cast iron (No. 16 iron) at 4.2 Kg/cm2 (60 psig) pressure on the surface of 3 samples of each test piece (except for test material 3, only 2 pieces of which were tested) for 4 minutes and recording the weight loss for each material. The following results were obtained.
Test Material 1 2 3 4
Weight loss (g) 2.7 0.10 3.2 2.0
2.6 0.20 3.8 1.8
3.1 0.17 - 1.9
Average weight loss 2.8 0.15 3.5 1.9
The iron-based titanium carbide alloy, 2, is clearly superior to the other materials.
Abrasive Wear Test
This test consisted of grinding each test sample by rotating it against a stationary steel disc in a container into which a slurry of 50 ml of water and 50 g of -140 mesh silicon carbide grit abrasive had been introduced. The test pieces were attached to a drill press actuated by a 2.3 Kg (5 Ib) load on a 15 cm (6") lever. The loaded sample was rotated at 250 rpm for 1 5 minutes. The loss of weight of the test piece was then determined.
Test Material 1 2 3 4
Weight loss (g) 1.37 0.24 1.3 0.59
1.44 0.14 1.2 0.60
These results show that the titanium carbide alloy in an iron-based matrix is clearly superior.
Hardness Test
The hardness of each material was determined by the standard test method of ASTM E-78-14,
Part 10-1975. The average of 5 test readings per sample are as follows.
Test Material 1 2 3 4
Hardness Rb90 Rc52 Rc52 Rc32
There was no loss in deposit hardness, as compared to the 50% tungsten carbide test material.
In order to determine the optimum concentration of titanium carbide in an iron-based matrix,
hardness was determined by the same method for several alloys. The results were as follows:
Alloy Composition Hardness
A 10% TiC+ 12% Ni+78% Fe-Cr-C Rc48
B 15%TiC+5% Ni+80% Fe-Cr-C Rc51.5
C 25% TiC+7% Ni+68% Fe-Cr-C Rc54
D 35% TiC+ 10% Ni+55% Fe-Cr-C N.A.
E 45% TiC+ 12% Ni+43% Fe-Cr-C N.A.
The deposits for alloys D and E, containing 35% and 45% titanium carbide respectively, developed cracks and were not tested further.
Based on all available test data, an alloy consisting of 5% to 25% titanium carbide and 5% nickel, balance an iron-based alloy matrix consisting of 29% chromium, 2.8% carbon, 0.1% manganese and 0.8% silicon, balance iron, provides substantially enhanced erosive wear resistance in comparison with prior art alloys, without sacrificing other qualities.
In addition to the chemical compositions of the titanium carbide alloys of this invention it has been found that the particle size distribution of the titanium carbide preferalby is -270 mesh by down
and, still preferably, from 10 to 20 ,um. With larger particle sizes, there is some loss of erosive wear
resistance and, with lower particle sizes, deposit efficiency is lost and with some titanium carbide
particles oxidation is experienced.
Moreover, it has been found that optimum results are obtained if the nickel component is -140 mesh and the iron-based matrix is -60+325 mesh. If the matrix is larger than 60 mesh, it will not feed well through common sizes of torch nozzles. Of course, this is not a problem if the plasma transferred arc system is not used. If the matrix powder is smaller than 325 mesh, oxidation of the matrix
particles tends to occur. Here again, if the plasma transferred arc system is not employed, the smaller
particle size is not a problem.
Although the tests were made on deposits applied by the plasma transferred arc system, any
other fusion depositing system can be used, including oxyacetylene welding, tungsten inert gas
welding (GTAQ) and plasma mig inert gas welding.
In addition to the above tests conducted on titanium carbide alloys containing an iron-based
matrix, alloys having nickel-based and cobalt-based matrixes also exhibit notably enhanced erosive
wear resistance.
A series of comparative tests was carried out on cobalt-based and nickel-based matrixes, in order
to compare then to one another and to iron-based matrixes, without the use of additional nickel as
described above. 6 different weight concentrations of titanium carbide from 5% to 60% with the
balance matrix were tested. Each test alloy was deposited as a flat layer to a generally uniform
thickness of 3 mm (1/8") on a 50x50x25 mm (2"x2"x1") piece of 1020 steel substrate by the use of
Linde's Plasma Transferred Arc System, Model No. PT-9-H.D., at 200 amps and 30 volts. Each test
plate was bombarded with chilled cast iron grit (No. 1 6) at 4.2 Kg/cm2 (6 psig) for 4 minutes and the
erosive loss of weight was determined.
The compositions of the matrixes were as follows:
Fe Base Co Base Ni Base
C 0.12 1.2 1.9
Cr 13.00 29.0 27.0
Mn 0.50 1.0 0.15
Si 1.00 1.0 1.50
Fe Bai 3.0 10.00
W 4.5 5.20
Ni 3.0 Bal
Co Bal 9.0
The matrixes had a particle size distribution of -60+325 mesh. The titanium carbide was -270 mesh by down (15 to 20 micrometres).
The hardness of each test plate was determined by a standard Rockwell hardness tester.
In this series of tests, the matrixes are well-known hardfacing alloys. The test results below demonstrate that the addition of titanium carbide to well-known hardfacing alloys greatly enhances their hardness and erosive wear resistance.

3. Deposits having 60% of TiC particles did not crack, indicating that high amounts of carbides can be used to obtain maximum hardness and erosion resistance.
4. Different matrix materials, such as iron-based, cobalt-based and nickel-based alloys, can be used to provide erosion-resistant deposits.
