Hardfacing Non-Ferrous Alloys

The prime function of Hardfacing materials is to protect a component or other material against the forces of wear.
Most hardfacing alloys are iron, nickel, or cobalt-base and can be used in a variety of forms including powder, solid welding rods or wires and tubular rods or wires. Continue reading

Dispersion Strengthened Copper (DSC) Alloys: Part One

Dispersion strengthening of any material is done with the aim to create a composite of superior physical properties via the dispersion of oxide particles in the metallic matrix.
High energy ball milling provides a repetitive fracture/weld method to achieve a homogeneous dispersoid distribution. Continue reading

Plasma Nitriding of Steels: Part One

Plasma nitriding improves the wear resistance of a material by effectively altering the surface microstructure while maintaining adequate substrate properties.
Nitriding occurs when a bias voltage is applied to the work piece causing ions to collide with the surface and consequently creating the nitride effect. Continue reading

The ROMELT Process

The Romelt process is born and driven by the ever present need to design effective steel and iron making processes which are much cleaner in respect to their environmental impact.
First industrial Romelt plant is currently being constructed in Burma and is expected to have a design annual capacity of 200,000 tpy. Continue reading
