SPC® Surface Protective Coatings

Our SPC® wear protection systems are used to protect against wear on components with metal surfaces that have too short a service life due to abrasion. These include, among others, wheels and rails of crane systems and storage and retrieval machines, as well as trunnions and riding rings of rotating equipment, such as rotary kilns, dryers or mixers. SPC® wear protection systems are continuously applied to the wearing surface by specially developed applicators and form a protective coating on the surface that minimizes the signs of wear.

Benefits


Benefits
The dry-based coating acts directly on the surface structure of the parts to be protected. Due to the strong mechanical adhesion to the metal surfaces, the protective film acts on all surfaces in contact. The surfaces are smoothed and the surface pressure on the material structure is distributed over a larger contact area. Thus, a wear reduction on metal surfaces of up to 80% is achieved.
Before

Before
If you look at a metal surface under the microscope, it shows simplified a surface structure like in this picture. In addition to various other factors this is one of the main reasons for wear on metal components. Due to the small actual contact area, a very high pressure is created here, which leads to material fatigue.
Wheel-Rail-Interface

Wheel-Rail-Interface
The profile of the wheel-rail-interface clearly shows how small the actual contact area of both surfaces is. This surface pressure leads to metal abrasion and metal flaking, which can be found typically next to the rail of any rail-bound equipment.
After

After
The wear protection element forms a firm bond with the metal surfaces (e.g. wheels or rails) and successively fills the surface with material.  This creates a homogeneous surface, which leads to an even distribution of the pressure. This significantly reduces wear.
The continuous application of SPC® coating maintains an optimum coefficient of friction between the contact surfaces. SPC® systems coat the metal surfaces with a very hard, solid protective coating, which increases or reduces the coefficient of friction depending on the application requirements. This is achieved by using different types of blocks with different additives.
Lubricant Blocks

Lubricant Blocks

TSB type blocks reduce the coefficient of friction between metal surfaces, with full wear protection. The coefficient of friction between two metal surfaces is reduced to as low as 0.05μ.

Application areas: wheels flanges, guide rollers, trunnions, thrust rollers.

Traction Blocks

Traction Blocks

The MSB type blocks increase the coefficient of friction between metal surfaces, but with full wear protection. Adhesion additives generate a coefficient of friction of up to 0.35μ.
By increasing the coefficient of friction wheel slippage can be reduced.

Application areas: railheads, drive wheels, driven support rollers.
