The wear resistance of both laser melted and conventionally quenched 1·0%C tool steel has been investigated. From unlubricated wear tests, the abrasion resistance of laser treated material was found to be superior to that of conventionally treated material, both in the as treated condition and after a range of tempering treatments (room temperature at 300°C), as a result of the presence of retained austenite.
