工程机械的工作条件恶劣,一些零件磨损很快,致使修理任务加重,配件需要量增大。为了改变这种状况,我们将等离子喷涂工艺应用于工程机械修复中,通过实际使用的考核,证明涂层的工作性能可靠,零件使用寿命延长,维修费用降低,是修复工程机械的一种好方法。 Poor working conditions of construction machinery, some parts wear quickly, resulting in increased repair tasks, increased demand for parts. In order to change this situation, we apply the plasma spray process to the repair of construction machinery. Through practical tests, we prove that the coating has reliable performance, longer service life and lower maintenance costs, which is a good way to repair construction machinery .
