TURBOCAM Offers Plasma Spray Coating
“There is a lot of pressure in the aerospace and automotive sectors to reduce costs,” said Jonathan Bicknell, General Manager of TURBOCAM Energy Solutions. “One way to do that is to bring certain processes in house. We have our proprietary TX1 process that benefits our automotive products by preventing wear, and now the plasma coating will provide the same wear protection to our aerospace products.”
Thermal spray techniques are coating processes in which melted (or heated) materials are sprayed onto a surface. In the plasma spray process, the feedstock to be deposited is a powder that is heated due to the energy (heat) released in creating a plasma jet. The plasma jet is created by passing an inert gas (Argon) through an electric arc emanating from the plasma torch causing the ionization of the inert gas. A secondary gas, such as hydrogen, can be introduced to increase the heat transfer properties. In the jet, where the temperature can reach 5,000° C (our process reaches 3,500° C) the material is melted and propelled towards a substrate. There, the molten droplets flatten, rapidly solidify, and form a deposit. The deposits remain adherent to the substrate as a coating.
The large numbers of technological parameters that influence the interaction of the particles with the plasma jet and the substrate directly affect the deposit properties. These parameters include feedstock type, plasma gas composition and flow rate, energy input, torch offset distance, substrate cooling, etc.
"TURBOCAM is the first NH-based company to be Nadcap® accredited for coatings,” commented Jonathan Bicknell, TURBOCAM Energy Solutions General Manager. "We are proud to be recognized for our commitment to continuous improvement."
The scope of the accreditation includes the following Nadcap® categories:
