Cost Reductions 

Wear and corrosion are of major concern to industry; they produce down time, loss of production, low efficiency, maintenance work and replacement parts. At the end of the year the cost affects the balance sheet and is an enormous drain on the economy.

The STRATA approach to combat wear and corrosion is to utilise alternative technologies (brazing, coating, welding or wearplate) and appropriate consumables, which satisfy the mechanical property requirements and simultaneously offer an effective barrier against the harsh environment.

Cost reduction: The STRATA approach is cost effective even though the barrier is highly alloyed (and therefore expensive) as the barrier is thin and only used where the attack is occurring. Producing the whole part from such a specialist alloy would not only be unnecessary and prohibitively expensive, but may be impossible to manufacture or fail to have the desired mechanical properties.

In-situ repairs: Frequently the cost of taking equipment apart to remove a failed part is greater than the cost of the part itself. It is more cost effective to avoid the strip down and repair the part in-situ. If the part is repaired or coated correctly it will also last longer.

The Mechanism of Wear 

The better you understand your problems, the easier it is for our experts to identify the unique solution to your particular needs.

Wear affects our everyday life. Take the car tyres that wear and have to be replaced regularly. The tyre gives us an idea of how broad and complex the wear phenomenon is as we know that tyre wear is influenced by many external factors such as driving speed, road surface, type of car and type of driver.

Wear can be thought of as a "system" incorporating several elements. The base body is the part experiencing wear (our tyre). It may be acted upon by an opposing body, either directly (the road) or via an intermediate body (broken glass on road). Wear may also be influenced by the environment in which the body operates (snow).

Wear is influenced by various factors or operating conditions:

• Movement (impact; sliding)
• Type of contact (sharp, flat, bearings)
• Load
• Type of materials (metal, sand, rocks)
• Speed
• Environment (corrosion; pressure; oxidation)
• Temperature

Components are rarely subjected to only one type of wear. When several different types of wear mechanisms are operating simultaneously, the result is combined wear and other parameters (pressure, oxidation, corrosion, impact or temperature) which can also influence the choice of protection technology employed.
