Process for producing bucket tappets and similarly stressed components in internal combustion engines

摘要

The invention relates to a process for producing bucket tappets and similarly stressed components in internal combustion engines, which are provided with wear-resistant, corrosion-resistant and thermal shock-resistant layers which are sprayed onto the base body by means of the plasma-spraying process with inert gas blanket or water blanket protection with at least twice sonic velocity of the plasma jet, and the body thus obtained being subjected to the hot-isostatic pressing process (HIP) at temperatures above 1000@C.
