arc deposited al-cr-o coatings having enhanced coating properties

摘要

Patent Summary: "Arc-deposited aluminum coatings having enhanced coating properties". The present invention relates to a method for coating aluminum layers with the aid of a pvd coating process. The pvd coating process is performed with the help of targets comprising al and cr which are embedded with each other. self-doping prevents the formation of oxide islands on the target during the reactive coating process.
