Surface Engineering
Research and Development

CASL has extensive surface engineering expertise and experience complemented by broad manufacturing capabilities that have helped operators prolong component service life and reduce asset owning and operating costs in the most challenging and severe industrial applications. Whether remanufacturing a worn component or protecting a new part, CASL’s engineering approach to the selection, application and finishing of metal surface coatings ensures component performance and service life meet client expectations, particularly in extremely difficult conditions.


Metal coating capabilities include:

Hard chrome and sulfamate nickel plating

• Proven, cost efficient method for wear corrosion and galling protection

• HEEF 25 chrome: low coefficient of friction, excellent surface finish 

• O.D. and I.D. applications  

• Optional nickel under chrome provides very cost efficient base metal corrosion protection  

Thermal spray

• High strength mechanical bond mechanism 

• High velocity oxygen fuel (HVOF), UHD ID HVOF™, air plasma and twin wire arc application systems, high energy combustion powder

• Fit for purpose broad range of materials and application systems to optimize the coating to the component operating environment  

• Significant range of coatings including tungsten carbides, chrome carbides, stainless steels, Inconels, Monels, Hastelloys, Copper and more 

• Common applications: mobile equipment suspension and hydraulics, downhole tools, production surface equipment, turbine spindles and more

Plasma Transferred Arc (PTA)

• Metallurgical, welded bond mechanism.  

• High energy, low heat, inert gas process that reacts minimally with base material and provides high resistance to wear 

• For severe abrasion and impact protection.  Coatings up to 0.375” 

• Typical applications: crushing cones, GET, slurry screens, stabilizers, kick pads, bearings and collars. 

Spray & Fuse

• Metallurgical, brazing bond mechanism.  

• Two step oxy-acetylene combustion process where the coating is first applied, then fused to produce maximum density and bond strength.  

• Minimal residual stresses greatly reduce potential for spalling. 

• Overlay thickness between 4mm and 25mm.  

• Suitable for extreme abrasion, corrosion and impact environments.  

• Typical applications: severe service slurry and tailing pipe, slurry valve liners, hydroheater spools etc.
