TeroCote 7888C
TeroCote® 7888 C has an excellent abrasion and corrosion resistance.
7888 C is a high-performance anti-wear product in the form of a flexible cord, comprising a nickel core wire, covered with an elastic binder containing a mixture of carbides and nickel alloy powder. The latter has a uniquely effective self-fluxing action, which gives 7888 C outstanding wetting properties. As a result, a smooth, even protective coat can be deposited quickly and easily. 7888 C deposits an extremely durable protective coating comprising a dense mass of ultrahard tungsten carbides embedded in a tough nickel-chromium alloy matrix. This structure offers extremely effective protection against erosive and abrasive attack by a wide variety of materials. The matrix composition helps to absorb moderate impact and improves resistance to corrosion, while the angular profile of the finely crystallised carbides makes ft very difficult to dislocate them from the matrix.

Applications
- Anti-abrasion protection
- 7888 C is designed to provide durable protection of large industrial components against wear by erosion and abrasion, for greatly increased service life. It can be applied on a wide range of carbon steels.
- Important: 7888 C is not recommended for high-manganese austenitic steels!
Industry Examples
- Oil exploration and extraction: drill bits, stabilisers.
- Brick/cement making: mixer and scraper blades, extrusion press screws.
- Mineral processing: conveyor or decanter screws, pump rotors and sleeves.
- Iron and steel: guides and scraper blades.
- Agriculture: cutting edges on ploughshares.
- Wear parts in cement industry
