Abstract
A method of measuring temperature reached by a part, for example a turbine engine part, in operation, the method including: mechanically treating the part; oxidizing the part; and depositing a layer including a temperature indicator for indicating the temperature reached by the part in operation.
Claims12
A method of treating a turbine engine part to permit deferred measurement of a temperature reached by the turbine engine part during operation, the method comprising:
- depositing a metallic underlayer on a substrate part;
- mechanically treating the metallic underlayer by sandblasting;
- depositing a first temperature indicating layer of at least two temperature indicating layers on the metallic underlayer;
- depositing a thermal barrier layer on the first temperature indicating layer, wherein the thermal barrier layer does not include a temperature marker;
- and
- depositing a second temperature indicating layer of the at least two temperature indicating layers on the thermal barrier layer, wherein
- the first temperature indicating layer includes the temperature marker for indicating and recording a temperature to which the turbine engine part is subjected in operation, and
- the second temperature indicating layer includes the same temperature marker as the first temperature indicating layer for indicating and recording a temperature of a gas at an outer surface of the turbine engine part.
