Iron-based compounds of varying chromium content. Applied by arc spray processes resulting in dense and homogenous coatings of medium to high hardness. Used for protecting functional surfaces of components against mechanical wear. With good resistance to abrasion, particle erosion and impact wear at limited corrosion resistance. Frequently used for repairs. The coatings can be finished mechanically by turning.

Applied by plasma spraying to protect functional surfaces against wear and corrosion. These homogenous and dense oxide-ceramic coatings possess good resistance when exposed to acidic and alkaline solutions and can be further augmented by sealing technologies. A wide variety of applications are possible owing both to the coating’s specific chemical-physical properties and to its diversity of mechanical finishes for obtaining specific surface conditions. Titanium oxide increases toughness and improves resistance to thermocyclic strain. Increased content of TiO improves mechanical workability but reduces electrical insulation and resistance to abrasion.

Protects metallic functional surfaces from wear and corrosion. This ultrapure protective coating is applied by plasma spraying and has very good resistance properties to acidic and alkaline solutions. Employed for heavy- duty sealing seats due to its excellent dynamic friction properties. The diversity in applications results both from particular chemical-physical properties and from various mechanical finishes for obtaining specific surface conditions.

Consists of a hard-metallic structure with a chromium carbide content of 75 % by volume, embedded in a metallic matrix of nickel and chromium. Applied by high-velocity flame spraying processes leading to ultra-hard and homogenous coatings of the highest density for protecting functional surfaces of components against mechanical wear and chemical corrosion attacks. Chromium carbides excel in high chemical and thermal stability. Embedding these in a non-corrosive and non-oxidising matrix of nickel and chromium results in wear-resistant coatings particularly suited for high temperature applications which have stood the test in the chemical and aviation industries in many cases. The hardness of such coatings is superior to those of electroplated hard chromium. The diversity in applications results both from particular chemical-physical properties and from various mechanical finishes for obtaining specific surface conditions.

Consists of a hard-metallic structure with a tungsten carbide content of above 80 % by weight, embedded in a metallic matrix of cobalt or cobalt and chromium. Applied by high-velocity flame spraying processes leading to ultra-hard and homogenous coatings of the highest density for protecting functional surfaces of components against mechanical wear and corrosion. The hardness of such coatings is far superior to those of electroplated hard chromium. The diversity in applications results both from particular chemical- physical properties and from various mechanical finishes for obtaining specific surface conditions.
