“Avoid the wearing away of parts and equipment due to mechanical or contact related forces.”

From Mining, Pulp and Paper, Converting, Chemical, Oil and Gas, even in the Medical Industries parts wear due to exposure to numerous types of wear; abrasion erosion, fretting, adhesive wear, fatigue and combinations of multiple wear.One of the biggest advantages of Wear and Abrasion coating is the wide range of substrates that can accept these coatings. This allows the user to design equipment made of a lighter and/or less expensive material and enhance the surface for better wear by using coatings.While thermally applied metal is often the first candidate for Wear and Abrasion, in many cases Polymers can meet the requirements for improved Wear and Abrasion resistance.

Mechanical Wear
The physical removal of a material from a solid surface by another solid surface or material. All manufacturing equipment that is exposed to Wear and Abrasion when of raw materials to finished good have wear issues. The types of Mechanical Wear and a list of the types of parts are:
  • Adhesive Wear
  • Abrasive Wear
  • Erosive Wear
  • Fatigue Wear

    Capabilities

    Adhesive Wear

    		Adhesive Wear takes place when two metal surfaces in relative motion with each other (sliding) are brought together under load causing the material from one surface to break loose and build up on the other surface damaging one surface or even both.Severe adhesive wear occurs when lubricant between tow surfaces break down and metal surfaces fuse together.
    Examples of Parts subject to Adhesive Wear:
  • Piston guides
  • Rings
  • Impeller Shafts
  • Armature Shaft Journals
  • Engine Bearings
  • Hydraulic Press Sleeves
  • Landing Gear
  • Chrome Replacement

    • Abrasive Wear

    		Abrasive Wear takes place when hard materials, metals, sand, grit and dust move along the surface under load indenting the surface. The surface material is removed by the abrasive media by gouging, chipping cutting or fatigue cracking.The abrasive medial can also become imbedded into the surface.
    Examples of parts subject to Abrasive Wear;
  • Piston Rods
  • Rod Liners
  • Couplings
  • Pump Parts
  • Stabilizers
  • Drill bits
  • Sucker Rods
  • Mining Equipment
  • Food Processing Equipment
  • Diesel Engine Saddle Blocks
  • Mud Rotors
  • Compressor Shafts
  • Ball Valves
  • Rollers
  • Guides
  • Screw Conveyors
  • Pump Housings
  • Knives
  • Guide Rails
  • Turn Bars
  • Silos
  • Pulleys for the wire industry
  • Eye Loops
  • Pneumatic conveying systems (Cutters, Elbows and Bailer).
  • Mixers / Mixer Ribbons
  • Floor Plates
  • Stair Treads

    • Erosive Wear

    		Erosive Wear take place when a particulate in a fluid stream impacts a surface with momentum causing material from the surface to be removed. High temperatures also accelerate the phenomenon.
    Examples of parts subject to Erosive Wear;
  • Pump Pistons
  • Diesel Engine Turbo Chargers
  • Impellors
  • Volutes
  • Bowl Bell Casings
  • Wear Rings
  • Rotary Valve Bodies

    • Fatigue Wear

    		Fatigue Wear occurs due to the repeated motion or cyclic stressing which can harm the surface. Cracks form at or below the surface and spread after repeated stressing by the bearing load.

    Examples of parts subject to Fatigue Wear;
  • Gears
  • Bearing surfaces
  • Shafts
  • Journals
