Sleeve bore, cylindrical sleeve, gear shaft and casing wear a uniform and scratches at between 0.02-0.20mm, should adopt high hardness, and parts combined with strong body, good wear resistance arc spraying repair processes. Arc spraying process: work surface pretreatment → preheating → spray adhesive primer layer paint job → → cooling → coating process. Then roughed roughened to provide surface compressive stress, increasing the area of ??coating and substrate binding and purifying surface, where to find hydraulic maintenance, reduce stress, hydraulic repair phone coating cooling, alleviate stress within the coating so conducive to increased adhesion. Sandblasting is the most common roughening process, Yulin hydraulic maintenance, sand with sharp, hard as well, hydraulic maintenance technician, the choice of quartz sand, silicon carbide and the like. After a fresh surface roughness can easily be oxidized or affected by environmental pollution, and therefore timely spraying, if placed over 4h will have to re-roughening treatment. Yulin hydraulic maintenance, Xi'an Chengtong hydraulic maintenance, where hydraulic maintenance provided by the Xi'an Chengtong hydraulic maintenance Limited. Yulin hydraulic maintenance, Xi'an Chengtong hydraulic maintenance, where hydraulic maintenance hydraulic maintenance Xi'an Chengtong Ltd.
