Since its introduction in 1924, Hard Chromium has been the benchmark by which all other electrolytic metal finishes are measured. It provides excellent wear properties, corrosion resistance, and low coefficient of friction. As an added service Nutmeg can polish chromium to a spectacular blue-white SPI A1.
The corrosion resistance of hard chromium is affected significantly by the condition of the base material. As with nickel coatings, the corrosion resistance of hard chromium is dependent on the quality of the barrier deposit provided prior to plating. Macroscopic and microscopic discontinuities must be minimized to provide suitable corrosion resistance. A properly ground or polished tool, plated with .00075" of hard chromium, that has a smooth homogeneous surface and is free of defects, will pass a 72-hour standard salt spray test with ease.
