Blasting is a surface processing technique in which spherical or granular materials made of metals or ceramics are jetted against substrate surface using compressed air. In this process, high speed colliding of blasting materials against the substrate surface produces crush the materials into fine particle which affect the durability of blast materials. However, there are no reliable investigations that consider influence of the durability of blast materials. This study investigated blast materials durability by examining relation between blast counts with particle distribution and changes in blast materials properties. Results from this investigation are summarized as follows: Particle size rapidly decrease with increase of blast counts. As a result, the removal quantity and surface roughness of substrate rapidly decreased.
