Selection of welding process for hardfacing on carbon steels based on quantitative and qualitative factors
TL;DR: In this article, an attempt has been made to determine the best welding process to hardface boiler grade steels based on quantitative factors (by measuring percentage of dilution) and qualitative factors (using the analytic hierarchy process [AHP]).

Understanding the Parameters Controlling Plasma Transferred Arc Hardfacing Using Response Surface Methodology
TL;DR: In this paper, the authors used response surface methodology (RSM) to predict and optimize the percentage of dilution of nickel based hard-faced surface produced by the plasma transferred arc (PTA) process.

Abrasive slurry wear behavior of stainless steel surface produced by plasma transferred arc hardfacing process
TL;DR: In this paper, the effects of operating variables such as abrasive particle size, slurry concentration, speed of rotation and slurry bath temperature on the abrasive slurry wear behavior of a stainless steel surface produced by the Plasma transferred arc (PTA) hardfacing process were analyzed.

Effect of experimental parameters on erosive abrasive wear behaviour of cobalt based (stellite) plasma transferred arc hardfaced surface
TL;DR: In this article, the effects of different experimental parameters such as specimen temperature, standoff distance, orifice diameter, air pressure and abrasive particle size on the erosive abrasive wear behaviour of cobalt based alloy (stellite) surface produced by plasma transferred arc hardfacing process were analyzed.
