Application of Plasma Cladding Technology in Repair of Hydraulic Support Column
The hydraulic support column parts traditional electroplating repair process has serious pollution,poor surface quality,short life.This paper studies the hydraulic support column parts repair process,put forward a kind of plasma cladding surface modification repair process and technology.Fe-Cr-Nb-Si-Mo alloy coating is researched-studied,and the surface is treated by electroplating technology and plasma cladding technology respectively.The results show that the surface hardness of the column obtained by electroplating process is 25~30 HRC,while the surface hardness value of plasma cladding is 60~75 HRC,with high surface hardness value,good wear resistance and corrosion resistance,which extends the service life of the hydraulic support,and achieves satisfactory experimental results.The research conclusion can provide a reference for improving the repair performance of the hydraulic support column.
