After boronizing of the samples, specimens were tested with optical microscopy and SEM analysis. Thus, the effects of powder size differences on coating layer were investigated. As a result of the examinations, i t has been identified that thickness, hardness and fracture toughness values increased with the decrease of boriding powder grain structure.
