Abstract

The present invention relates to particles made from a High Speed Steel (HSS) that is modified to contain dispersed precipitations of manganese sulfide (MHSS), and to a Powder Metallurgy (PM) method using the same. It also relates to a part produced by the PM process using the modified HSS particles. It has been found that by forming a melt of a HSS and 1 ) Mn or a Mn-containing compound and 2) S or an S-containing compound, followed by an atomization process, modified HSS particle can be obtained containing dispersed sulfide precipitations containing mainly manganese sulfide. The amount of Mn and S are chosen such that the weight ratio of Mn to S (Mn/S), in wt-% of the total weight of the particle, is in the range of 8.0 - 1.0, preferably 5.5 to 3.0, such as from 5.5 to 3.5 or from 5.5 to 4.1. An article obtained by a PM manufacturing method using the particles has improved machinability as compared to a an article prepared from a corresponding non-modified HSS to which 1) Mn or a Mn-containing compound and 2) S or an S-containing compound were not added. Surprisingly, the physical properties of the article obtained from the modified HSS particles are not or not significantly impaired as compared to an article that is prepared from corresponding non-modified HSS particles.

Abstract

A laser cladding or plasma transferred arc overlay welding process may be used advantageously to apply and to control the material properties of a coating designed for protecting the substrate against wear, corrosion and oxidation at elevated temperature. Furthermore, a laser cladding or plasma transferred arc overlay welding process may be used to apply the coating alloy materials in applications where traditional thermal spray or weld-applied coatings are not practical. By using these welding methods very good bonding is achieved by fusion during welding. At the same time the properties of the clad layer is preserved by the limited dilution typical of these two welding methods compared traditional overlay welding, by e.g. Gas Tungsten Arc Welding and the like.
