In Aviation manufacture industry almost 75% of the engine components, turbine blades and moving components are coated with some kind of protective barrier to ensure maximum performance in the lowest weight ratio. The primary functions of thermal spray coatings in the aero industry are thermal barriers, high temperature corrosion resistance, abradable and high wear resistance at high temperatures. Shafel Tech is supplying coatings for Hindustan Aeronautical Ltd., Bangalore since 2000.

Steel Industry equipment is subjected to extreme conditions of heat, cyclic shock, metal friction, corrosive atmosphere and above all severe wear in a relatively short period of time. Hence Steel Industry equipment and handling machinery requires excellent surface protection characteristics not only to withstand the extreme conditions but also to give sufficient life to make the process of steel making cost effective.

Today's machinery used in Paper & print Industry process very high speed production. The rollers used in the machinery are subjected to severe wear & corrosion by ink and other particles. The gripping of paper is subjected to severe wear and the gripper looses it gripness, hence high strength coatings are required to withstand erosive wear but maintain roughness. Other rollers require low coefficient of friction and to prevent wet paper, adhesives, ink from sticking to rolls surface.

Components in this industry are subjected and exposed to sever wear, heat & corrosion. Many parts are coated with Thermal spray coating to act as excellent high hardness & high toughness barrier to these conditions. Primarily piston rods, shafts & sleeves when worn out by a few hundred microns will lose its applicability in this industry.

In Thermal Power industries there are various moving parts subjected to high heat, corrosion and wear. Hard surface thermal spray coatings act as an excellent barrier to save from material degradation and thus enhance life.

The high hardness wires when subjected to drawing or size reduction will cause the tools which are instrumental in their production like wire drawing drums and pulleys subjected to severe sliding wear and cutting load on the surface. Hence these surfaces have to be protected from high sliding wear resistance. Normal hardened metallic surfaces cannot withstand the stress & cutting wear of the high speed wires over even for a short period of time, hence hard face coatings acts as an excellent barrier for wear and thus enhance life and tool productivity.

Very fine cutting wear is pronounced in the Textile Industry as kilometers of fibrous material pass though metallic components. The components should have very low coefficient of friction to prevent easy flow of fibers and prevent breakages. Compaction Rollers in Fabric (100% cotton knitted fabric) compaction and shrinkage / pressing of fabric in lengthwise direction. Open width and tubular compacting machines use coated rollers.

For heavy duty vehicles and for vehicles used in highly abrasive atmosphere thermal spray coatings act as an excellent wear resistant barrier for longer life and performance enhancement at high speeds and heavy load conditions.

Various sleeves and shafts and the pump used in slurry conditions are subjected to high erosive wear and cannot withstand the conditions even for a few months. These components are thermal spray coated to extend life and withstand the application. Rotary air lock Valves used in abrasive media require very hard uniform coatings to maintain the air gap in the valve for effective function (prevent leak)
