Wear protection

What exactly is wear?

Wear is the increasing wear and tear of components or impairment of their functionality.

The surface of the counter body is gradually eroded by mostly intensive mechanical (grinding, rolling, hitting, scratching) as well as chemical and thermal stress. This loss of material / mass impacts the geometry of the components chainging and impairing their function. This damages components, which can lead to machine failures. Wear reduction is an important condition for increasing the service life of such systems and save on costs and raw materials.

A distinction is made between ordinary and extraordinary wear. While the ordinary, in principle foreseeable and unavoidable wear, results from repeated and permanent stress, the extraordinary wear occurs more or less by accident (overloading or incorrect operation of machines). This undesirable change in the surface often occurs, for example, on ball bearing slewing rings, but also on product-contacting parts such as mixing tools. These components are often easy to replace and are also grouped under the term "wear parts".

"Hardfacing & soldering" - the most common wear protection application

The short video shows the activity of hardfacing. This refers to the application of wear protection using an oxyfuel torch. The flame of an acetylene-oxygen mixture is used to heat the often “soft” base body and melt the cored wire used. In a viscous state, the material is applied to the areas to be protected, sometimes several times, in order to obtain a wear-resistant and impact-resistant layer when cooled.
The base body is also heated during soldering. The connection between the individual carbide plates and the base carrier is created using solder.

Wear materials

In order to counteract the material erosion on mixer tools or other highly stressed surfaces of machines or system components, we provide these components with a suitable wear protection.

Successfully used wear materials:

  • Stainless steel
  • Special tungsten carbide
  • Chilled cast iron
  • Aluminium oxide
  • Silicon carbide
  • Polycrystalline diamond
  • Hardox®, XAR®
  • Polyurethane
  • Composite armour
  • Tungsten carbide

The processing methods used by our specialists include the following

  • Armouring
  • Soldering
  • Welding
