Thermal Metal Spray

Cormac has been actively involved for 23 years in the application and development of thermal arc spray (metal spray) throughout Australasia for use in the prevention of corrosion to steel and steel in concrete utilising the application of metals such as zinc, aluminium, zinc aluminium alloys and Nickel, Stainless Steel, Hastalloys, Monel and Bronze.

We currently have offices in Sydney, Malaysia & Indonesia….but we work all through Australasia. 

Cormac has developed unique mobile equipment & plant for all onsite Thermal Metal Spray and Cathodic Protection applications. The company boasts having more than 12 high deposition thermal metal spray systems and numerous abrasive blasting units that can mobilise any where throughout Australasia.

Our thermal metal spray applications are used for corrosion prevention, cathodic protection (Thermally Sprayed Anodes), Non Skid (RMS approved) and abrasion & wear resistance and component rebuilding (winch drums etc), with projects ranging from every day structural steel fabrications to dams, ships, bridges, mining, oil refineries & offshore oil, gas & drilling facilities.

Thermal metal spraying is widely recognised as one of the most superior coatings available for providing corrosion resistance together with extremely long service life and life cycle costing. 

Twin wire thermal arc spraying involves the melting of 2 wires and propelling the molten or plasticized metal particles toward an abrasive blasted substrate. There the particles instantaneously solidify to produce a dense metallic coatings.

These coatings can be applied to thicknesses of 500µm plus. Most metallic coatings provide a service life relevant to their thickness typically meaning the thicker the coating the longer the service life. Metallic coatings can provide a service life from 5 to 50 years plus and in the harshest of environments. The most profound advantage of metallic coatings being they require no ongoing maintenance during their projected service life unlike that of traditional paints.

Our Thermal Metal Spray process is also used as an alternative to hot dip galvanising. Metal spray ‘galvanising’ does not induce great heat or distortion and can be selectively applied, used for repairs to existing hot dip galvanising, applied to any thickness for greater localised protection or masked to protect vital components… item is too big for us….

Cormac also provides Thermal Spray Operator and equipment maintenance training in Indonesia, Malaysia and Australia. The courses are in-depth and provide the trainee with the technical and practical expertise to carry out complex thermal spray applications, and as an applicator, conform to ISO 14918 and DNV approval.
