Definitions

  • FIG. 1 is a vertical sectional view of a diffusion coating set-up pursuant to the present invention.
  • TD nichrome containing about 20 percent chromium, 2% Th0 the balance nickel can be similarly diffusion coated with chromium. Good results are obtained with the TD nichrome when the chromium pickup in the coating is only about 30 to about 40 milligrams per square centimeter. However, the diffusion of chromium into the TD nichrome is slower than in TD nickel so that about the same treating temperatures and times are used.
  • Other forms of dispersion-strengthened nickel and nichromes such as zirconia-strengthened and hafnia-strengthened nickel show the same type of improvement when coated in the above manners.
