Abstract
The laser deposition method of medium-carbon steel and medium-carbon alloy steel surface includes the following steps: blank-forging-mechanical machining-heating treatment-mechanical machining-laser deposition-mechanical machining it turn. Its blanks is medium-carbon steel or medium-carbon alloy steel, and its deposition material is Ni-WC or Co-alloy or Co-Cr-WC; and the technological condition of laser deposition is: laser output power is 3.5-4.0 KW, laser beam spot size of (25X30)X2 sq.mm, out-of-focus quantity is 40-48 mm, scanning turning radius of laser beam is 100-1300 mm, line speed is 2.1-4 mm/s, angle speed is 3 deg./s and deposition material powder-feeding rate is 400-450 mg/s. As compared with existent die the service life of die prepared by said method can be raised by 5-8 times.
Description
Technical field
The present invention relates to a kind of metal surface treating method, particularly a kind of middle carbon copper, medium carbon alloy steel surface laser cladding method.
Background technology
Existing steel formability roll, roll forging mould etc. all adopt the high-carbon high-alloy steel manufacturing, complex treatment process, and work-ing life is low, and causes product quality problem.
The employing laser melting and coating technique at die surface, is new technology with the cladding of sintering metal cladding material, and it can in very large range realize improving the work-ing life of roll, mould.If but still use high-carbon alloy steel as the stock of roll, mould, to cause in the laser cladding process occurring much being difficult to the defective that overcomes, as cladding layer crack, blank such as roll ftractures in laser cladding process etc., show very poor manufacturability, cost can be very high simultaneously, and technological process is also very complicated.Adopt medium carbon steel, medium carbon alloy steel to do blank, can overcome above-mentioned shortcoming, and can obtain good result of use.
Summary of the invention
The purpose of this invention is to provide a kind of middle carbon sodium, medium carbon alloy steel surface laser cladding method.
The present invention's method is carried out in regular turn according to the following steps;
Blank → forging → mechanical workout → thermal treatment → mechanical workout → laser melting coating → mechanical workout;
Above-mentioned said blank is medium carbon steel, medium carbon alloy steel;
The content of kind, element and the element of the cladding material that above-mentioned said laser melting coating is used is:
The processing condition of above-mentioned said laser melting and coating process are:
| Laser output power | 3.5～4.0kw |
| Beam spot size | (25～30)×2mm 2 |
| Defocusing amount | 40～48mm |
| Laser beam flying speed (turning radius 100～130mm): | Linear velocity 2.1～4mm/s, 3 °/s of circular frequency |
| Cladding material powder feeding rate | 400～450mg/s |
| Blank | Medium carbon steel, medium carbon alloy steel |
The present invention is applicable to steel plate shape roll, mould, roll forging mould, hot-extrusion mold.
The mould that use the present invention's method is made, its life-span is improved 5～8 times than existing mold; Manufacturing cost and original mould are suitable, have improved product percent of pass; Save mould Installation and Debugging man-hours, reduce product cost, use that blank can not ftracture in the process of this method, cladding layer can not crack.
