The composition of specimens was 3% Cu. +. 0.2% C. +. balance Fe%. Tensile strength, hardness values and surface properties of treated specimens were determined. Boronizing. +. shot peening surface treatment was found to be the most convenient surface treatment for P/M steel materials based on test results. However, it is important to avoid high peening intensities for shot peening of boronized surfaces because shot peening deteriorates the boronized surface of P/M steel specimens. As a result, surface hardness values such as 1800-2500 HV were achieved after boronizing, the difference between the matrix materials with a hardness of 200 HV was quite high. © 2010 Elsevier B.V.Article10.1016/j.powtec.2010.08.007
