Hardfacing Process

Superior carbides concentration, high quality, low cost and exceptional durability against wear, are all achievable through CeraMetal’s Hardfacing Process.

CeraMetal’s Hardfacing Process has been developed and perfected in-house so as to optimise the various parameters and steps for manufacturing Wear plates. The basic hardfacing process, involves the use of hardfacing wire with an alloy powder mixture. The generated electric arc melts both the wire and the alloy powder, leading to the formation of metal carbides in the weld bead.

Through applied research & development, CeraMetal has managed to optimise this hardfacing process so as to achieve consistent quality and resource-efficient production. The uniqueness of our process is further consolidated by the use of CeraMetal’s plate hardfacing machinery, developed and built in-house by the company’s engineering department.

01 Low cost
02 Consistent quality
03 High carbide
04 Excellent wear

Quality-from raw materials, to product components and all the way to finished products -is a crucial aspect of our everyday operation. Quality Control and the full range of our systematically designed internal processes, ensure that our products consistently meet quality Standards and customers’ expectations.
