“…Hence, for small scale applications, a semiautomatic process like gas metal arc welding (GMAW) may be useful as compared to the other highly automatic processes, In addition to this, GMAW machines are now easily available as compact portable machines that require less initial set-up and less running cost. A strict control over heat input and dilution can be obtained through an advanced GMAW process, which decreases transition zone thickness and thereby prevents micro cracks [11]. Rozmus-Gornikowska et al [12] have performed Inconel 625 coating on P235GH steel and found a better bonding between nickel based coating and base metal through GMAW.…”

Ni-Cr-Si-B alloy deposition on 304 ASS is executed by making use of automated processes like PTA, laser cladding, etc., which are supportive in the mass production. However, for repairment and job-specific works, such processes become more expensive and hence cost-effective pulse-GMAW process is proposed. The effect of current on the coating characteristics is investigated. Microstructure reveals a eutectic structure near interface, which changes to a hypereutectic near the top surface. γ -Ni, carbides and borides phases are observed in coating, which increases hardness (529.3 HV 1.0 ) and wear resistance (20 times). The present study reveals an inverse relation of hardness and wear resistance with current due to increased iron content in coating at higher current which suppresses boride formation.

“…Generally, the alloy is a combination of one primary metal, (called the solvent) to other minor metal, (called the solute) or one metal to another element. The earth's crust consists of 2.7% of magnesium and it is recyclable material with low density and good machinability (Liu, et al, 2017). This study specifically concentrates on Magnesium alloy, MgAZ91D.…”

MgAZ91D is an alloy which has high general strength, low density and high formability. Therefore, magnesium alloy, MgAZ91D is widely being used mainly in the aerospace, automotive and telecommunication industries. The main disadvantage of MgAZ91D is its low resistance towards corrosion attack. Therefore, this research objective is on improving the corrosion-resistant of magnesium alloy, MgAZ91D. Nitriding process surface heat treatment on the MgAZ91D substrate by subjecting the metal alloy with 95% nitrogen and 5% hydrogen gas environment in a heating chamber. The variables are time of exposure and temperature of the surface heat treatments. The nitrided samples will undergo immersion corrosion test to analyse the corrosion-resistant of the specimens. Further analysis on the microstructure formation, case depth and corrosion resistance correlation based on the test matrix. The experimentalsetup will determine the correct procedure and conclude the impact of surface heat treatment towards the corrosionresistant of MgAZ91D and improvement of the alloy. .
