Wire arc spray is a variant of thermal spraying process where two conductive metal wires are fed independently into the spray gun. These consumable wires are electrically charged and an arc is generated between them when it comes in contact with each other. The molten material is atomized into small particles and propelled at high velocity onto the desired substrate by compressed air to form corrosion & wear resist layer. ATS has expertise and proven track record for application of wire arc spray coatings for atmospheric & chemical corrosion. Over the years, we have developed customised coatings for components and equipment of Paper mill, Boiler, Petrochemical, Oil & Gas industries. What is Thermal Spray? Thermal spray is an industrial coating process that heats or melts metallic or ceramic materials and deposits them onto a surface. It is used for surface enhancement or surface remanufacture. How Does Thermal Spray Work? Thermal spraying uses heat, depending upon the metallurgical properties of the coating material, and various carrier gases, depending upon the thermal spray process. Each process has different benefits as the result of these temperatures and process characteristics. A thermal spray process should be carefully selected depending upon the desired coating characteristics such as; wear resistance, corrosion resistance, thermal barrier, and many more. Other factors include: size and shape, substrate material and the operating environment of the component. Each spray process has strengths and application limits.
