Description
Technical field
The invention belongs to field of material technology, more particularly to a kind of preparation method of wear-resistant overlay welding alloy material.
Background technology
Metal ceramic compound wear resistant resurfacing welding material is made up of soft carcass metal and cermet particles, is had high wear-resisting
Property and higher shock resistance, have been widely used for oil, coal, geology and mine etc. industry in some seriously ground
Damage the built-up welding of workpiece working face.Hardfacing alloy powder includes the alloy systems such as cobalt-based, Ni-based, iron-based, due to cobalt-based and Ni-based conjunction
Bronze end is expensive, therefore iron-based alloy powder material is using more.Iron base composite material is relative to traditional high-abrasive material
For, there is good toughness, plasticity, can be as the first choice of high-abrasive material.Currently used iron base composite material it is wear-resisting
Property be mainly mutually WC and TiC, but if using WC based ceramic metals as wear-resisting phase, then have that wearability is relatively low, cracking resistance
The deficiencies of ability.And though use TiC based ceramic metals are low with density as wear-resisting phase, modulus of elasticity, hardness and intensity are high,
The advantages of high-temperature oxidation resistance, corrosion resistance and wearability are good, but due to the weldability of TiC based ceramic metals and carcass metal
Wetability it is poor, the mobility in molten bath is bad during built-up welding, causes cob webbing, and overlay cladding is easy when long-time uses in addition
It is cracked.
The content of the invention
The purpose of the present invention is to be directed to above-mentioned the deficiencies in the prior art, there is provided a kind of preparation side of wear-resistant overlay welding alloy material
Method.
The method of the present invention is carried out according to the following steps：
By granularity the ferrochrome of 70 ~ 140 mesh, ferrotianium, vanadium iron, CeO, ferro-boron, molybdenum-iron, aluminium powder, ferronickel, TiN, sodium KP1,
Carbon black and iron powder are well mixed, and are subsequently placed in briquet in mould, natural air drying at least 24h, then under the conditions of 50 ~ 60 DEG C
0.5 ~ 1h is dried, then 1 ~ 5h is incubated under the conditions of being warming up to 150 ~ 300 DEG C.
In the above method, the ratio by mass ratio of each composition is ferrochrome 30 ~ 40%, ferrotianium 1 ~ 3%, vanadium iron 6 ~ 10%, CeO 2 ~
4%, ferro-boron 5 ~ 7%, molybdenum-iron 6 ~ 8%, aluminium powder 2 ~ 5%, ferronickel 3 ~ 7%, TiN powder 8 ~ 10%, sodium KP1 2 ~ 4%, carbon black 3 ~ 5%,
Surplus is iron.
Carbon arc built-up welding or plasma surfacing are carried out using the wear-resistant overlay welding alloy material of the present invention, operating method is simple, into
This is cheap, easier than manual build up welding wear resistance electrode acquisition high carbon content and high rigidity, the overlay cladding of high-wearing feature, hard phase and matrix
It is firmly combined with, there is very high abrasive wear resistance, application is quite varied.
