Cleaning of parts is a process of heat treatment,and improper cleaning often leads to quality problems in practical work.Incomplete cleaning before chemical heat treatment leads to uneven infiltration layer in the later stage.The residual salt on the surface of the workpiece after salt furnace quenching is not thoroughly cleaned,resulting in corrosion of the workpiece.During the quenching and cooling process,improper cleaning timing resulted in cracking of the workpiece.Incomplete cleaning can contaminate the e-quipment and cause discoloration in subsequent surface treatment.The various reasons for the malfunction are analyzed and the three measures of awareness education,document control and technical improvement have been formulated.By enhancing the quality awareness of all employees,implementing system control and the application of automatic cleaning equipment,the cleaning process of the heat treatment process has been standardized to avoid quality problems.
