The AOA MK2 Process
Through intensive research and development in process control and overlay metallurgy, Australian and Overseas Alloys has developed a proprietary, computer-aided cladding process for the exclusive manufacture of AOA MK2. This innovative process, combined with a proprietary and unique alloy system, automatically controls the critical parameters necessary to achieve the optimum in Carbide Size and Distribution. It also allows for minimum dilution, thereby maintaining maximum hardness throughout the full thickness of the overlay. With this state-of-the-art computer technology, consistent, high quality AOA MK2 overlay is guaranteed, Everytime!
DISADVANTAGES OF STANDARD CLAD PLATE
- Lower alloyed overlay deposited with high heat input results in soft, diluted interfacial zone
- Decreased base metal support for reduced impact loading
- Slow cooling rate results in large carbides that dislodge upon wear and impact, thereby accelerating wear
- Lean chemistry results in fewer total carbides
ADVANTAGES OF AOA MK2
- Higher alloyed overlay deposited with low heat input resulting in minimum and maximum interfacial hardness
- Increased base metal support for greater impact loading
- Faster cooling rate results in smaller, finely dispersed carbides prolonging wear life
- Deposit chemistry with increased chromium and carbon results in more carbides.
