Birchwood Casey has developed a new finish for iron and steel components with a low temperature, environmentally friendly process that serves as a low-cost replacement for polluting cold blackening. The Microlock AO process forms a non-toxic aluminum oxide conversion coating that is 1.5µ thick, silver/black in color, and tightly adherent to the metal surface. When sealed with a rust preventive, the finish is said to provide robust corrosion protection that is better than cold blackening at half the cost, and without undesirable pollution hazards. Potential applications include: tooling and machine components; automotive parts including tierods,

ball joints, clutch and brake components; and large components such as oilfield drilling

equipment. Microlock AO yields a nondimensional silver-black finish, corrosion protection and anti-galling properties. According to Birchwood Casey, Most cold blackening lines can be easily converted to the process.
