The laser cladding layer on the surface of the high-manganese steel frog manufactured by WILA is made of 431Co40 powder cladding to the top surface of the high-manganese steel frog. The single-layer cladding thickness of the laser cladding layer is 0.5~1.0mm. The thickness of the cladding layer is 5~7mm. The laser cladding layer can be closely combined with the high manganese steel frog matrix, has strong hardness and wear resistance, and can withstand the impact load of train wheels.
WILA's surface modification method is easy to operate, suitable for industrial production and promotion, and the product stability after cladding is strong, thereby stepping up the market applicability of ultra-high-speed cladding technology, which can effectively solve the traditional solution strengthening treatment In the early stage of operation, the high-manganese steel frog cannot withstand the impact of high-load trains due to its low hardness.

High manganese steel railway turnout frog repair
Product description：
Name: High-manganese steel turnout fork core
Material: ZGMn13
Basic situation: The hardness of the new high-manganese steel frog is 200HV, and the surface hardness gradually reaches 400HB (Hrc43) after the impact of the wheel during use. Before reaching the secondary hardness, it is easy to wear about 5mm on the surface of the front end of the fork core at 0-100mm due to the low hardness of the wheel and the high impact force. Make the front end of the fork core lower.
Laser repair requirements:
1. The hardness is 400HB, and the mechanical performance testing (strength, hardness, impact, metallography, bonding) is performed in accordance with national standards, and the ideal thickness is 5MM.
2. High manganese steel material has high carbon content, and carbides are precipitated at high temperature, which is not conducive to metallurgical fusion and is easy to form brittle and hard structures.
