WEAR RESISTANT THERMALLY SPRAYED LAYER, ITS FORMATION AND SLIDING MEMBER COATED WITH THE WEAR RESISTANT THERMALLY SPRAYED LAYER

摘要

PURPOSE: To form a thermally sprayed layer excellent in wear resistance and seizing resistance. ;CONSTITUTION: The wear resistant thermally sprayed layer is formed on the inner circumferential face of a cylinder liner made of steel. This thermally sprayed layer is constituted of steel contg. 0.25 to 2.2% C and ≤13.0% of one or ≥two kinds selected from among Cr, Mo, W and V, furthermore, in which unmelted grains are dispersed into the matrix by 10 to 50% area ratio, and moerover, the hardness of the unmelted grains and matrix is different, and that of the higher one is regulated to ≥400HV.;COPYRIGHT: (C)1996,JPO
