The present study was undertaken to clarify the relationship between the wear resistance and structure of deposited iron alloy containing high-carbon and high-vanadium. In order to study the effect of size and distribution of vanadium-carbide and surface condition on the wear resistance of the alloy, vanadium-carbide and in the specimens were controlled from 8 to 55% in volume. Measurement of the wear properties was done using a specially designed apparatus. Specimens were tempered at various temperatures. The results of observation are summarized as follows : (1) Under the condition which brings a large amount of wear, the alloy including big size vanadium-carbide particles. On the other hand, the alloy including fine vanadium-carbide was better under the condition which brings a little amount of wear. (2) In wear properties, the alloy including vanadium-carbide was superior to the alloy including chromium-carbide. (3) Effect of heat treatment on the wear resistance was distinguished remarkably under the condition which brings a large amount of wear. Influence of the amount of vanadium-carbide on the wear resistance was more notable in annealed specimens than quenched-tempered specimens. (4) Change of the wear resistance resulting from change of hardness was more remarkable in low hardness alloy than in high hardness alloy. (5) In the alloy including large amount of vanadium-carbide, the wear resistance scarcely changed by heat treatment.
