| Abstract: | The working performance of Ni-P and Ni-Co alloy coating of HT200 gray cast iron gear's tooth surface was studied. Utilizing the electronic microscope and optical microscope an analysis upon surface appearance, interface organization of longitudinal section, compositions of alloy coating and micro-hardness etc. was carried out. Testing result of contacting fatigue shows that the coating could enhance notably the contacting fatigue life. |
