Abstract

The problem occurrence of burns of titanium compressor blade are considered. The methods of burns-control is considered. The automated device of measurement of a contact potential difference is developed. The technique of not destroying burns-control of blade on change of electron work function , a contact potential difference measured by a method is developed.

Keywords:
