Metal Finishing, Coating & NDT Insights

Grit blasting is an abrasive surface preparation process used to clean and profile metal before a specified finishing operation. When blasting is appropriate for the part and coating system, it helps create the surface condition needed for the next process. At Sub Source in Rockford, Illinois, grit blasting is one of several metal preparation and

In the aerospace industry, there is no margin for error. Aircraft components operate under extreme conditions—high stress, temperature fluctuations, corrosion exposure, and constant vibration. As a result, every process involved in manufacturing and finishing aerospace parts must meet the highest standards for quality, consistency, and traceability. That’s why NADCAP certification plays such a critical role

Black oxide treatment, also known as blackening or blackening steel, is a process used to create a black, corrosion-resistant surface on ferrous metals (usually steel) and sometimes copper, brass, and other materials. This treatment involves the formation of a black iron oxide layer on the surface of the metal. Not only does this provide a

CARC stands for Chemical Agent Resistant Coating. It is a type of paint used by the military to provide protection and resistance against chemical and biological agents, as well as decontamination procedures. CARC paint is designed to make it easier to decontaminate military vehicles and equipment that may be exposed to chemical or biological contaminants
