随着热喷涂工艺的日益发展,尤其用于尺寸修复表面,涂层的精加工就成为重要的技术关键。国外有关资料推荐用磨削精加工,根据我院对磨削加工的试验研究,涂层内孔磨削的生产效率低。我院改用电解磨削加工多种涂层内孔的工件,选择相应的喷涂层加工的电解液及电加工规范,经实际验证,达到了加工精度,且生产率还能大大提高。 As thermal spray processes continue to evolve, especially for size-repaired surfaces, finish finishing becomes an important technological key. Abroad, the information recommended grinding finishing, according to our hospital on the grinding process of the pilot study, coating the inner hole grinding production efficiency is low. Our hospital to use electrolytic grinding processing a variety of coating hole in the workpiece, select the appropriate spray coating processing of electrolyte and electrical specifications, the actual verification, to the processing accuracy, and productivity can be greatly improved.
