SPRAY COATING PROCESSES

Optimal Trajectory Planning for Spray Coating

The Evolution of Coating Processes

Today’s coating processes provide the capability to produce anti-reflective (AR) coatings, bandpass filters, separation filters, high laser damage threshold coatings, mirror coatings, etc. with high precision and high yields. The production environment is based on batch-coating processes and component sizes that range from mm to meter. Generally, one function such as limited wavelength coverage...

An Optimization Of Spray Coating Process To Minimize Coating Material Consumption

In cookware industry, interior spray coating process is an important process to protect the cookware product from the corrosion. In this process, the coating material “TEFLON” is used to spray to cover all the part’s surface. If a pot or pan is not too deep, one spray gun is enough to spray to cover all the interior surface. However, for the high side-wall pot, two spray guns must be used to sp...

Numerical (CFD) Analysis of Thermal Spray Coating Process

Corrosion of Cold Spray Deposited Copper Coating on Steel Substrates

The corrosion behavior of copper cold spray coatings on a carbon steel substrate was compared to that of commercially available wrought copper under the conditions anticipated in a nuclear waste repository. Corrosion potential and linear polarization resistance measurements were conducted over 90 d to 120 d in 3.0 mol/L NaCl under anoxic (1) and oxygenated-toanoxic (2) conditions to simulate th...
