Experimental Study on Wear Resistance of On Line Heat Treated U20MnH Rail
The characteristics and change rules of wear behavior for rail with different load conditions are analyzed through experimental study on wear of on line heat treated U20MnH rail combining with the morphology features of wear sur-face and profile for samples observed by microscope and scanning electron microscope.The results showed that the wear loss of on line heat treated U20MnH rail was significantly reduced with increase of load under load conditions of 1 200 N,1 500 N and 1 800 N respectively.
