THE EFFECT OF HEAT TREATMENT ON THE WEAR RESISTANCE OF A NICKEL-PHOSPHORUS COATING,

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 m/sec) 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)
