Arc spray
Venture Engineering
What is arc spray? Arc spray uses electricity and the heat of a current arc to melt wire material. Arc thermal spray systems continuously feed two wires into a gun assembly where the wire is heated. These two wires can be the same material or two different materials. This includes the use of cored wire to form special alloys for better wear or corrosion characteristics. Compressed air propels the coating onto the desired surface creating a durable metal coating. Due to the high heat and spray velocity, arc coatings can be laid down quickly and economically. 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.
