Growth of visible oxide films on metals at moderate to high temperature. Decomposition at still higher temperature
Visible oxide films on metals insulate contacts. They have to be ruptured, better yet avoided by use of noble metals, or by operating contacts of base metals in vacuum or in a non-reactive atmosphere. Details of the growth of oxide films beyond 100 Å at elevated temperature is of minor interest in contact work. A short summary will suffice.
