Embodiment 1
[0027] The piston rod surface reinforcement layer composite process provided by the present invention goes through the following steps:
[0028] A. Pour industrial-grade alcohol and acetone on the working surface of piston rod 1 of the hydraulic transmission cylinder with medium-carbon quenched and tempered steel as the body to remove oil and impurities;
[0029] B. Adopting a conventional pneumatic powder feeding device, the 18-8 type austenitic stainless steel powder with a particle size of 100 meshes is delivered to the piston rod 1 working surface of the A step with argon gas with a purity of 99.99%;
[0030] C. Under the rotational speed of the piston rod 1 at 600mm / min, use a conventional laser to irradiate the equipment, and within the spot range with a power of 3.5KW and a bandwidth of 3mm in diameter, the laser irradiates the 18- on the working surface of the piston rod 1 in step B. Type 8 austenitic stainless steel powder, cladding the stainless steel powder on the w...
