Type of deposit

Thermo chemical ceramic

MNI offers the Placrox II, thermochemical ceramic, based on chromium oxide whose resistance to corrosion is many times greater than for conventional deposits by plasma spraying. This coating with a hardness of 2000 Vickers, ranked food, can be deposited in the bores and is perfect for wearing parts.

Our Thermo chemical ceramic are waterproof and no surface porosity. It is possible to make linings of small diameter (3 mm min.) And external to a length of 2.50m and a diameter of 400 mm. The Placrox II and diamoxyde expands as the base, with a temperature resistance up to 700 ° with dip the substrate in cold water without changing the structure of the coating.

PLACROX II process:
13 cycles allowing to increase in hardness and to decrease in porosity at each cycle:
1. Machining the piece
2. Preparation of a slurry based on the base metal
3. Application of the slurry
4. Thermal treatment at 535 ° C
5. Alternate 6x Impregnation and heat treatment at 535 ° C
6. Hooning the piece
7. Alternate 7x Impregnation and heat treatment at 535 ° C
8. Hooning
9. Polishing
