Abstract: This paper discusses the feasibility of using the Langmuir probe as a diagnostic tool for plasma in Vacuum Arc Coating (VAC) processes, and the validity of probe theories in this situation. A system has been set up for the in situ diagnosis of VAC plasma. Plasma parameters have been diagnosed nuder various process parameters.

Key words: Langmuir probe, vacuum are coating, plasma diagnosis
