INVESTIGATION OF WEAR RESISTANCE OF WELD METAL AND THE ECONOMIC EFFICIENCY OF THE COMBINED METHOD OF RECOVERY OF CYLINDRICAL PARTS
Study of wear resistance of cylindrical parts, welded with different wires and processed by various methods was conducted. Technal-economic comparison of the effectiveness of the combined method for restoring of worn cylindrical parts is made. For example, the recovery of the roller spring for suspension of locomotive VL-80 was considered.
