Fig. 4 Fabricated turbine blades
The cutting edges of a gas turbine are to be fitted cautiously to the plates [14,
15]. This is served by the edge root which is either welded or fixed to the circle
circuit. The temperature consequences for the sharp edge and the plate ought not to
cause extension because of high temperature and ought not prompt any detachment
or disfigurement of the connection.
4 Experimentation
The experimentation has been carried out using the fabricated blades painted with
the selected thermal paint and it is exposed to a constant heat source.
4.1 Selection of Thermal Paint
A multichange thermal paint MC 350-8 has been selected for the analysis of surface
temperature. The initial colour of the paint is red and colour changes when the paint
is exposed to temperature more than 3500 °C. The colour change of the paint at
different elevated temperatures is shown in Fig. 5.
4.2 Painting of Blades
The fabricated blades shown in Fig. 4 have been sprayed with MC 350 as shown in
Fig. 6. The initial colour of the paint is red. The painting of the blades is done by
nozzle spray in order to maintain the thickness of the paint film within 0.5 µm (or)
