Abstract
Using new technologies like near net-shape spray forming is possible to obtain quickly nozzle type refractory components. Material utilisation and very high and laborious machining can be avoided. In order to achieve nozzle type components plasma spray technique has been used to spraying molybdenum powder onto a preshaped substrate. The influence of plasma spraying parameters on the mechanical and physical properties of free-standing components has been studied. The residual stress was also evaluated in order to know their behaviour and working ability under difficult conditions.
Keywords: thermal spraying, nozzles, burness, near net-shape components
