Description

Coating deposited in HVOF processes, using our HVOF systems, effectively isolate the metal surfaces from aggressive corrosive atmosphere, and provides high resistance to erosive wear caused both solid particles (ash and other combustion products) and liquid (condensing water vapor).

HVOF sprayed carbide based coatings provide excellent protection against very severe abrasive wear and erosion. One of the most successful applications - protection against solid particle erosion (SPE) and water droplets erosion (WDE) of the steam turbine LP blading.

The HVOF process creates extremely dense coatings with bond strengths in excess of *0,**0 PSI.  A distinct advantage of the HVOF process includes the ability to produce very low surface roughness.  This frequently results in easier and faster finishing - many times eliminating it completely.  Further more, HVOF coatings produce a very predictable and homogeneous chemistry.

Examples of Other Practical Industrial Applications:

·  Very dense wear resistant ceramic coatings - excellent wear resistance (mechanical seals, power generation industry, textile industry, mining)

·  Wear resistant oxide and carbide coatings for the protection for textile industry machinery components (thread guides, rollers) against abrasive wear of the thread

·  High temperature erosion resistance of various aircraft, power generation and automotive components

·  Wear/erosion protection of various steel mill components, including rolls

·  Slurry pump components, sleeves in particular

·  Medical coatings - coatings for implants and laparoscopic instrumentation
