Plasma Thermochemical Surface Engineering

We have recently commissioned a Rubig Micropuls-Plasma Furnace which enables Metaltech to implement several plasma assisted surface engineering treatments.

PLASNIT Surface coating treatment carried out in a pulsed plasma environment using Micropluls technology enables nitriding by nitrogen/hydrogen mixtures or nitrocarburising by the addition of a hydrocarbon (such as methane) to the ionised gas mixtures.

For optimum corrosion resistance the nitriding and nitrocarburising process can be followed by a PLASOX treatment. When the nitriding is stopped water and oxygen can be added under pressure. The result is oxidation of the surface producing magnetite (Fe₃O₄) which has a very high corrosion resistance.
