Conclusion

  1. 1.

    Chemical nickel plating of titanium increases its anti-friction quality.

     
  2. 2.

    When two surfaces with a nickel coating 20–40μ thick are fitted together the pressure at which grabbing begins is 180–200 kg/cm2 and the friction coefficients are respectively 0.12–0.15 for the thinnest layer (20μ) and 0.15–0.30 for layers about 40 μ thick.

     
  3. 3.

    When the thickness of the coating is increased, grabbing begins at lower pressures (80 kg/cm2 and the friction coefficient increases to 0.3–0.4.

     
  4. 4.

    When nickel-coated titanium is fitted to a surface of unhardened titanium the pressure at which grabbing occurs is about 80–100 kg/cm2 and the friction coefficient is 0.15–0.35.

     
  5. 5.

    Galvanic coatings of chromium, etc., can easily be deposited on titanium coated with nickel.
