Birchwood Casey’s MicroLok AO is an environmentally friendly alternative to cold blackening on iron and steel components that offers better corrosion resistance and decreased operating costs, the company says.
The non-toxic, aluminum oxide conversion coating does not use EPA-regulated chemicals such as copper and selenium, which are used in cold blackening. Process rinse waters are non-hazardous and do not require waste treatment, the company says. The coating also features anti-galling protection to aid in assembly and startup;
temperature stability as high as 1,400°F; operation at 120-140°F with no boiling or splattering; no scale or sludge buildup in tanks; and bath maintenance consisting of only pH monitoring.
Applications include tooling and machine components; automotive parts, including tierods, ball joints and clutch and brake components; and large components, such as oil field drilling equipment.blog comments powered by Disqus
