Plasma Transfer Arc

In 1996 Austral Technologies purchased and installed the largest Plasma Transferred Arc (PTA) system in the world.  This marvel of German ingenuity is able to deposit up to 25kg/hr of Tungsten Carbide hard-facing.  In 2015, Austral Technologies installed a second fully automatic PTA system of the same capacity, and in 2024 we commissioned our third PTA system.  These PTA machines are the largest in the Southern Hemisphere which gives Austral Technologies an unmatched manufacturing capacity.

Metal Spray Surface Coating

Metal Arc Spraying (MAS) is one process in a short list of mechanically bonded surface engineering deposits.  Although not a complete metallurgical bond, MAS can produce bond strengths of around 9,000 to 10,000psi.  Austral Technologies combines metal arc spraying with specialised surface engineering deposits to combat abrasion, corrosion and erosion in a variety of environments.  

Chromium Boride deposits are regularly Metal Arc Sprayed onto components such as boiler tubes and economizer tubes for coal fired power stations to combat high temperature erosion.  While Chromium Carbide or Complex Chromium Carbide deposits are can be sprayed onto components subject to fine particle erosion and thermally sprayed aluminium (TSA) is regularly sprayed onto pipes and valve bodies to protect against the elements and corrosion under insulation (CUI).

Reclamation and Rebuild

Many mining crushing, pulverising and mineral processing component only ever wear away a small percentage of their bulk before becoming unusable. This is where Austral technologies' Reclamation and Rebuilding experience can offer major cost savings.

By reclaiming and or rebuilding worn components with superior wear resistant materials, the need to replace old with new is negated. In actual fact, it is even improved upon. Austral Technologies' superior surface engineering products and services provide longer life and performance enhanced wear characteristics at a more economical price.

On site and in situ

For many years, Austral Technologies has been providing on-site and in-situ reclamation services to both the power generation and mining industries.  Whether it be hard-face rebuilding a primary crusher mantle on one of Australia's mine sites or hard-face rebuilding coal pulveriser mill rollers and tables in Australia or south east Asia, Austral Technologies has the equipment, materials and technical expertise to complete On-site and In-situ Reclamation projects to high quality and planned schedule.
