zinc phosphatingの例文


  1. Manganese and iron phosphating coatings are usually the thickest electrochemical conversion coatings, being thicker than electrochemical conversion coatings such as zinc phosphating and bluing.
  2. Somewhat analogous to the improved manganese phosphating process improvements discovered by Baker and Dingman, a similarly improved method was found for an improved zinc phosphating process as well.
  3. Subsequently, an alternative technique was developed by the Parker Company to utilize easier-to-obtain compounds at less expense through using zinc phosphating ( Parkerizing ) in place of manganese phosphating ( Parkerizing ).
  4. The patent for this zinc phosphating ( Parkerizing ) process ( utilizing strategic compounds that would remain available in America during a war ) was granted to inventor Romig of the American Chemical Paint Company in 1938 as, just prior to the loss of easy access to manganese compounds that occurred during World War II.
  5. With these process improvements, the end result was that a low-temperature ( energy-efficient ) zinc phosphating ( Parkerizing ) process, using strategic materials which the United States had ready access to, became the most common phosphating process used during World War II to protect American war materials such as firearms and planes from rust and corrosion.
