STUDY OF MATERIALS TEST METHODS FOR WEAR RESISTANCE IN OIL AND MINING INDUSTRY

The main cause of damage to oil and gas equipment is wear. This paper proves that the principal wear mechanism is abrasive and shock-abrasive wear; and analyzes materials test methods and techniques for wear rate identification. The author considers standardized and non-standardized methods and establishes that despite a large number of materials test methods, we don't have a unique one for adequate assessment of wear resistance in metals. It is concluded that selection of test methods depends on working conditions of the equipment and use of different types of wear to assess resistance of metals
