[CN 201710395070.5] Method for repairing hammer head of precision forging machine by laser cladding
[CN 201710395070.5] A Method for Repairing Hammer Head of Precision Forging Machine by Laser Cladding Title: A Method for Repairing Hammer Head of Precision Forging Machine by Laser Cladding Application Number: CN 201710395070.5 Applicant: North University of China Application Date: 2017-5-30 Patent Type: Invention Application for a Method for Repairing Hammer Head of Precision Forging Machine by Laser Cladding, it is a transition alloy layer composed of 17.5 ~ 19% Cr, 10~12.8 Co, 6.3~7.5 Mo, 1~2.6W, 1.6~2.5 Al, 0.23~0.29 C, 2.1~2.9 Ti, 0.23~0.38 B and the balance Ni on the surface of the hammer head of the precision forging machine, A surface alloy layer comprising 13-16.8% Mo, 14-18% Cr, 4-5.62% W, 4.3-5.8% Si, 8.2-9% Fe, and up to 0.15% C, up to 1.2% Mn, up to 0.028% S, up to 0.019% P, up to 2.7% Co, and the balance Ni is then laser clad on the transition alloy layer. The repair method of the invention can reduce the amount of wear of the hammer head of the fine forging machine under the strong wear of the forging high temperature, delay the crack expansion rate of the cladding layer, and improve the service life of the hammer head of the fine forging machine.
