Abstract
Heating apparatus specifically adapted for the heat treatment of turbine blades comprises two support parts (10, 11) which may be pivotally connected by a hinge (17), the support parts (10, 11) carrying heating elements (14, 15) and a slot (20) the provision of the slot (20) enabling the heating apparatus to be slid over the trailing edge of the turbine blade into position on the blade and subsequently closed by a closure member (24) which enables the rapid application of heating apparatus for heat treatment processes which has hitherto been a complicated and time consuming operation. The heating apparatus may incorporate thermocouples (27) and heat sinks.
