Coating

Placrox II

MNI offers the Placrox II, a thermochemical ceramic, based on chromium oxide whose resistance to corrosion is many times greater than conventional deposits by plasma spraying. This coating with a hardness of 2000 Vickers, ranked food compatible, can be deposited in the bores and is perfect for wearing parts of rotating machines, metering pumps, Food pumps, transfer rollers, collars of baggers, columns cylinders, mechanical seals, pistons, … Possibility to realize complete parts from drawing or model.

The coating may be realized on any substrate: steel, cast iron, stainless steel, titanium, allowing the latter to withstand high temperature in air without alteration of the material.

FOR MORE INFORMATION

Wearing parts of engines, pumps, compressors, dispensers can be coated in Placrox II, either originally or in repair. The advantage of treating a piston rod or a pump or compressor jacket is triple, since there is a reduction of friction, resulting in a significant improvement of the behavior of rubbing parts antagonists, trim, braids or segments ensure a longer life of the rod or sleeve, with a significant reduction in energy cost during startup and during operation.

The Placrox II is waterproof and has no surface porosity. It is possible to deposit the coating on small diameters (3 mm min.). The Placrox II expands as the base material, offering a coating without cracks. Placrox II can resist to a temperature up to 700°C. Even dipped in cold water there will be no change in the structure of the coating.
