**8. Application of thermal spray technology for the protection from wear**

A large range of industrial parts get advantage from thermal spraying, whether it is a portion of the manufacturing processes or as reclamations or re-engineering techniques. Some materials are used for minute role applications and others are sprayed by the tonne. Every application utilizes an amalgamation of procedure and

Reclamation and re-engineering of a wide range of rotating and moving parts from machines of all kinds, including: vehicles of both railways and highways, ships, aerospace, printing industries, paper industries, chemical industries, food industries, mining, earthmovers, machine tools, landing gear (chrome replacement) and any apparatus which is subject to wear, erosion or corrosion. This is done using either arc spray, flame spray or HVOF systems to spray steels, nickel alloys, carbides, stainless alloys, bronzes, copper and many other materials. New components which benefit from the enhanced surface properties that thermal spraying provides, include: Gate and ball valves, rock drilling bits, and down hole tools, print rollers, fluid seals, aerospace combustion chambers, turbine blades. Thermal sprayed coatings are used on a vast range of components which operate in harsh surroundings where, erosion, wear, corrosion or high temperature reduce part life.

Part life is significantly prolonged due to thermal spray processes.
