Heat and thermo-chemical treatment of metals
We specialise in providing heat and thermo-chemical treatment services, i.e. ion nitriding, which we carry out using a JONIMP 900/500 machine. Ion nitriding is a modern process used to increase the surface hardness of steel. The technology is used in many areas of the economy, including the automotive, aerospace and energy industries, for structural and tool components exposed to abrasive wear and corrosion during operation. We also have at our disposal, a two-chamber vacuum furnace RVFOQ-224 with heating chamber dimensions of 600x400x280 mm, enabling bright heating of the charge to 1200°C and quenching without contact with air, with the possibility of cooling in nitrogen or oil. Our staff have many years of experience in these areas and are committed to earning the trust of our customers.

Vacuum hardening and its advantages
Hardening is a heat treatment process for steel, carried out to increase the hardness of the workpiece, as well as to improve strength and wear resistance. This type of heat treatment is carried out at different temperatures, depending on the type of steel.
Tempering is used to increase the fracture toughness of the hardened steel and to remove the stresses created during hardening.
Vacuum hardening takes place in a vacuum, so there is no oxidation effect and no weakening of the workpiece. The method allows very rapid heating and cooling of the workpiece material, so that the desired results are obtained more quickly. Vacuum hardening is used when high purity, a metallic surface and low material distortion are required.
Ion nitriding and its advantages
Nitriding is a thermo-chemical treatment process that consists of saturating the surface layer of the treated steel with nitrogen, consequently obtaining a layer of a uniform thickness, which makes it possible to increase the abrasion resistance of the treated material. Ion nitriding of steel increases its hardness, fatigue resistance and resistance to corrosion. The process is also characterised by low deformation of the workpieces. The low brittleness of the nitride layer makes the obtained workpieces extremely durable. Ion nitriding is faster than conventional nitriding techniques and can also be carried out at lower temperatures (as low as 350°C) with reduced pressure.
