General Applications:

• Repair and Reconditioning
• Erosion preventing coating
• Anti-Corrosion
• Heat Shield
• Erosion Prevention
• Insulation

Deposit materials mainly used are:

• Steel
• Tungsten Carbide
• Chrome Carbide
• Ceramics and Plastic Composite

Our Techniques are as follows:

• Flame Spraying
• Plasma Spraying
• High Velocity Oxygen Fuel
• Arc Spraying
• Thermal spraying

Advantages:

• Rebuilding provides a smooth, wear - resistant surface with a low co-efficient of friction
• Especially for crankshafts which require a hard surface on the crankpins and main journals, thermal spraying is the best build-up method
• It is a "Cold" process, the risk of heat warp age by welding and the need for subsequent straightening is eliminated
• A prime financial benefit of this application is in saving the replacement cost of the components and in some cases, saving the replacement cost of the engine itself, when new parts are not obtainable
• Depending on the local cost of labour, the cost of repairing of the crankshaft will vary. But having repaired so many crankshafts our experience shows that replacement cost of components is very economical.
