Pulsed current plasma transferred arc hardfacing
Journal of Materials Processing Technology, 2006Abstract Hardfacing is used to enhance surface properties of a metallic component, as a specially designed alloy is surface welded to achieve specific wear properties. Surface properties and quality depend upon the selected alloy and welding process.

The wear behavior between hardfacing materials
Metallurgical and Materials Transactions A, 1996Hardface weld cladding in industry most commonly uses cobalt-based STELLITE nos. 6 and 12 and nickel-based Colmonoy nos. 56, 83, and 88 for plasma transferred arc (PTA) welding of 4140 steel. Frictional and abrasion wear of weld layers are compared with that of the widely used nitridized, low-level SKD61, SACM1 steel alloys and with centrifugal-cast ...

Hardfacing for Wear, Erosion and Abrasion
2013Weld overlay coatings also known as hardfacing is a method which involves solidification for applied coatings. This method is as old as welding process and was first applied by J.W. Spencer in 1896. This technique offers unique advantages over other processes in that the overlay/substrate weld provides a metallurgical bond which is not susceptible to ...

Casing Wear Caused by Tooljoint Hardfacing
SPE Drilling Engineering, 1986Summary Casing wear caused by new tooljoint hardfacings, such as fine-mesh tungsten-carbide hardfacing and a hardfacing covered with a layer of relatively soft material, has been investigated in the laboratory. The tests were performed on a full-scale test facility with field conditions—forces, motions, and fluids—simulated as closely as

HARDFACING: NOT MERELY A REClAMATION PROCESS
Surface Engineering, 1995Billions of pounds are lost every year in industry as a result of worn parts and wastage of materials. In view of the need for energy and materials conservation, the hardfacing of parts or components must be considered as a production process from the design stage, rather than merely a reclamation process.

How to Select a Hardfacing Alloy
SAE Technical Paper Series, 1983<div class="htmlview paragraph">Selecting the right hard-facing alloy for the job is not as difficult as it may seem if one just follows a few simple steps. First, determine the composition of the part and the type of weld deposit that is needed (must it be machinable, crack-free, etc.); secondly, determine the wear pattern the part is likely to ...
