摘要： A method of making sintered components made from an iron-based powder composition and the sintered component per se. The method is especially suited for producing components which will be subjected to wear at elevated temperatures, consequently the components consists of a heat resistant stainless steel with hard phases including chromium carbo-nitrides. Examples of such components are parts in turbochargers for internal combustion engines.

摘要： The present invention relates to an iron-based alloy that is able to provide a coating on a substrate, the coating having simultaneously high hardness and wear resistance. The iron-based alloy consists of 3.0-7.0% by weight Cr; 1.3-3.0% by weight C; 0.2-2.0% by weight B; 2.0-10.0% by weight V; optionally 1.5% by weight or less Si; optionally 1.0% by weight or less Mn, optionally 2.0% by weight or less Mo; optionally 1.5% by weight or less Ni; the balance being Fe and unavoidable impurities.
The present invention further relates to an article comprising a substrate and coating formed thereon, the coating being formed from the alloy, and to a method for forming a coated article. The method preferably employs HVOF, laser cladding or plasma cladding.

摘要： Particles made from a High Speed Steel (HSS) that is modified to contain dispersed precipitations of manganese sulfide (MHSS), a Powder Metallurgy (PM) method using the same, and a part produced by the PM process using the modified HSS particles. 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. 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.

摘要： A material which can be used to manufacture components which exhibit high strength and high wear resistance, at the same time possessing reasonable ductility. The material also has cost advantages compared to other potential metal powder solutions. An iron based powder composition which achieves desired microstructure/properties and associated sliding wear resistance with reduced content of expensive alloying ingredients such as admixed elemental Ni and Copper.

摘要： A new iron-based powder containing a plurality of composite particles composed of a ferritic iron or iron-based porous 5 structural particles having at least one particulate friction modifier distributed in the pores and cavities of the structural particles and further containing at least one particulate stabilizer-sealer. The composite particle is especially suited to be used as a functional material in friction formulations such as brake pads and enable replacement of copper or copper-based materials used in such friction 10 material formulations.
