Effect of surface hardness on the wear resistance of steel 40Kh under hydroabrasive wear
This article presents equations which can be used in the selection of optimal correlations of the hardness of the surface layer of steel 40Kh and the abrasive filler in the design and manufacture of components of oil-well equipment operating under conditions of hydroabrasive wear. An experiment was conducted to determine the relation of the surface hardness of steel 40Kh to wear resistance under hydroabrasive wear in a slurry stream. The test conditions were: velocity of the hydroabrasive stream of 15 m/sec, abrasive concentration in the slurry of 50 g/liter, quartz abrasive sand from the Karadag sand pit with a grain size of 0.2-0.315 mm and microhardness of 11,000 N/mm/sup 2/, medium of technical water, and test duration of 5 h. It is determined that the approximation of the relation of the amount of wear of steel 40Kh to the surface hardness by means of a curvilinearregression equation makes it possible to determine more accurately the nature and amount of wear of steel 40Kh under hydorabrasive wear in a slurry stream.
