High-Carbon Fe-based Alloys for Coatings

01

Description

JSC POLEMA, Russia's largest manufacturer of metal powders, offers a diverse range of powder alloys and pure metals produced by various methods, including high-pressure gas and water atomizing, oxide reduction, and mechanical grinding.

Recently, the company has been actively implementing new technical solutions for gas atomizing, which significantly improve the morphology of particles, reduce the number of satellites, and increase the fluidity of powders and the quality of weld coatings.

Atomized powders produced by JSC POLEMA are classified into two groups: powders for coatings and structural powders.

The first group includes over 200 types of powders for coatings using various methods, including self-fluxing nickel, iron, and copper alloys, tool steels, high-carbon and low-carbon steels and alloys, corrosion-resistant and heat-resistant steels and alloys, as well as tin- and zinc-based composite powders and alloys.

The variety of available powders for coatings, used in high-speed, detonation, gas-flame, and plasma spraying, gas-powder, plasma, induction, and laser welding, allows to solve specific problems of surface hardening and effective protection against wear and corrosion of machines and equipment parts operating under elevated temperatures, high mechanical stress, and with abrasive substances and in aggressive environments.

The second group includes structural powders, such as pressed powders of pure metals (chromium, molybdenum, tungsten, nickel, and titanium), copper-based alloys (bronze and brass), stainless steels, special alloys with high magnetic permeability (permalloys), and materials for shot jet processing of parts (tool steels).

Powders of this group are used for making sheet rolled products, bars, and non-ferrous and refractory metal forgings, tools, sintered and deformed parts, composite materials used in electrical engineering, electronics, tool engineering, machine engineering, aerospace industry, nuclear power engineering, vehicles, filters, gas absorbers, and other engineering areas.
