TeroCoating® - TLS 241 Chrome steels, FeCrC

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.

TeroCoating® - TLS 245/295 FeCrNiB (TLS245), FeCrNiMoCSi (TLS 295)

Iron based alloys for corrosive loads are characterized by a high chromium content making these alloys specially suitable for applications in corrosive mediums. In addition to the good corrosion protection properties, these materials are very well adapted to the sphere of wear protection, as together with the high level of toughness provided by the matrix, a high hardness of carbides and borides is also attainable. Both alloys are applied using the high velocity flame spraying process permitting the achievement of very dense coatings which can therefore be applied very thinly. The coatings can be further machined by both turning and grinding, enabling various roughness values up to Rz < 0.3μm. Through the use of favourable alloying elements these coating systems are significantly more economical than pure carbidic materials.

TeroCoating® - TLS 324 Aluminium oxide – titanium dioxide Al2O3-TiO2

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.

TeroCoating® - TLS 334 Chromium oxide Cr2O3

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.

TeroCoating® - TLS 415 Chromium carbide Cr3C2 - NiCr

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.

TeroCoating® - TLS 425 Tungsten carbide WC-Co, WC-CoCr

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.

TeroCoating® - TLS 455/465 WC-FeCrAl (TLS455), WC-NiMoCrFeCo (TLS 465)

Tungsten carbide in special matrixes consists of a hard metallic structure with tungsten carbides in proportions above 80 %/weight embedded in a metallic matrix from an iron based (nickel-free) or a nickel based alloy. These material combinations can be used in particular for products for which cobalt and nickel are to be avoided but for which as well as the superior wear properties of the carbide, outstanding corrosion protection is to be guaranteed. Treatment using the high velocity flame spraying processes results in the most dense, homogenous and ultra hard coatings which protect the functional surfaces of components against mechanical wear and corrosion. The hardness of these coatings is far superior to that of galvanically deposited hard chromium. Their range of application is highly versatile through their specific chemical-physical properties plus the possibility to produce special surface qualities through various kinds of mechanical processing
