Abstract:

Steel 45 was coated in acid solution with Ni-P coating. Afterwards specimens were held for 1 hour each in electro-vacuum furnace at 200, 350, 400, 450, 500, and 600 degrees. The wear resistance under load of 30-70 kg. was determined on a rotating machine MI rate of revolution 0.47 msec by using as control the gray cast iron specimens. The weight was determined before and after each 1000 m wear length. The wear was C 30, 45, and 70 kg loads at 400 degrees 0.6,1.,1.4 at 500 degrees 2.3, 4.2, 5.6 at 600 degrees 3.1, 5.4, 6.1 mg. weight loss. Heat treatment had significant effect on the physical properties of Ni-P coating the wear resistance is highest after heat treatment at 400 degrees. Author
