Abstract

The present invention relates to a composition comprising certain iron alloy particles (A2) in combination with other high melting alloy particles (A1), in particular high speed steels and cobalt-based alloys, the iron alloy particles (A2) having a lower melting point than the high melting alloy particles (A1). The use of the particles (A2) in a sintering manufacturing allows broadening the process window and to obtain sintered parts having a high density, high hardness and high strength under various process conditions. This is particular useful for the PM manufacture of high melting alloys such as tool steel (including high speed steel (HSS)), which are otherwise difficult to process.

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

The present invention relates to a new pre-alloyed metal based powder, intended to be used in surface coating of metal parts. The powder is deposited using e.g. laser cladding or plasma transfer arc welding (PTA), or thermal spray (e.g. HVOF). The powder is useful for reducing friction and improving wear reducing properties of the deposited coating. Such coatings may also improve machinability. As friction or wear reducing component, inclusions of manganese sulphide or tungsten sulphide in the pre-alloyed powder may be used.

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.

Abstract

The invention relates to powder metallurgy, in particular production of tungsten monocarbide spherical powders, which is a major component of metalloceramic hard alloys used for manufacture of tools, drill bits, steel alloying, wear- resistant coating cladding at elements operating in intensive wear conditions. The method includes melting of the starting material, and melt atomization with forming of spherical powder. As starting material a tungsten monocarbide grit is used. Melting and atomization of the material is implemented by continuous filling of grit into a rotating crucible of a centrifugal atomization device under an inert atmosphere and melting it by a plasma arc. After that an annealing of the obtained powder is made at a temperature of 1200-1400°C during a time necessary for W2C breakup with subsequent cooling of the powder in a furnace. The invention is directed to production of tungsten monocarbide spherical powder with WC content of more than 70 %.

Abstract

Disclosed is a new diffusion-bonded powder consisting of an iron powder having 1-5%, preferably 1.5-4% and most preferably 1.5-3.5% by weight of copper particles diffusion bonded to the surfaces of the iron powder particles. The new diffusion bonded powder is suitable for producing components having high sintered density and minimum variation in copper content.

IPC Classes  ?

  • C22C 33/02 - Making ferrous alloys by powder metallurgy
  • C22C 38/16 - Ferrous alloys, e.g. steel alloys containing copper

Abstract

The present invention concerns an iron-based powder composition comprising, in addition to an iron-based powder, a minor amount of a machinability enhancing additive, said additive comprising at least halloysite. The invention further concerns the use of the machinability enhancing additive and a method for producing an iron-based sintered component for easy machining.
