Method of producing combustion engine piston involves immersing ring support in fluid metal bath and coating it with metal powder

摘要

Before the piston is cast , at least a ring-support of the piston is dipped into a fluid metal bath, after being coated with metal powder, such as aluminum or nickel powder, and heated. Before coating, a cooling duct plate is placed against the ring support. Heating is carried out with a HF spool or flame-spray method.
