The laser melting coating reproducing method of creeper tread.The present invention mainly gets rid of fatigue layer to the creeper tread of abrasion, then carries out
Crack detection, Co-based alloy powder and silicon carbide powder are then mixed in proportion, crawler belt is synchronously sent to using powder feeder
Plate surface, using semiconductor laser by powder melting on creeper tread matrix, be finally machined out, so as to meet creeper tread
Use requirement.
Technical scheme is as follows：
(1) surface of creeper tread is cleared up, surface abrasion position and its wear extent of creeper tread is determined, according to detection
As a result, the fatigue layer of crawler belt plate surface is removed.Creeper tread to be repaired is cleaned repeatedly using absolute ethyl alcohol and acetone, removed fusion
Greasy dirt and the corrosion at position are covered, and carries out drying process；
(2) magnetic powder inspection and ultrasonic examination are used to creeper tread, it is ensured that it is without surface and internal flaw.
(3) Co-based alloy powder is prepared, the alloy powder prepared is put into three-dimensional meal mixer and mixed 2~3 hours；
(4) creeper tread is fixed on high-power semiconductor laser cladding numerical control machine for processing, carried out using powder feeder same
Powder feeding is walked, is scanned using high power semiconductor lasers cladding, by Co-based alloy powder cladding in crawler belt plate surface, cladding process
Middle use inert gas shielding；
(5) creeper tread after laser melting coating is machined according to drawing and about technical requirements, reach size and
Required precision；
(6) surface dye penetrant inspection is carried out to the creeper tread after processing, detected whether defective, it is ensured that the surface matter of creeper tread
Amount reaches criterion of acceptability.
(7) mass percent of each composition of Co-based alloy powder described in above-mentioned steps (3) is：Ni60 86%,
SiC14%.The granularity of alloy powder is 150~300 mesh；
(8) the laser melting and coating process parameter set by above-mentioned steps (4)：Rectangular light spot is 2 × 8mm, laser scanning speed
Spend for 360~540mm/min, overlapping rate is 30~40%, the scan power of semiconductor laser is 2000~3000W；
(9) protective gas described in above-mentioned steps (4) is argon gas.
The present invention has the following advantages that compared with prior art：
1st, technique is simple, energy-conserving and environment-protective, cost are low, it is possible to achieve creeper tread is repeatedly remanufactured.
2nd, the creeper tread after remanufacturing has more preferable wearability, corrosion resistance and anti-fatigue performance, reduces and uses into
This, with prominent economic benefit and social benefit.
3rd, than manual welding and built-up welding, laser melting and coating process operating efficiency is high, and processing performance is good, and can reach preferably makes
Use performance.
4th, the creeper tread after being remanufactured using laser deposited nickel-base alloy powder end improves 1.5 compared with the life-span that traditional handicraft is repaired
More than times.
