“…COF was about to be 0.373, However, TiC composite layers, varying between 0.236 and 0.33. Siva et al [16] examined the effect of PTAW Process Parameters of Nickel coating on Corrosion behaviour. They reported decreased Pitting phenomenon when welding current increased Also, Other parameter like oscillation width indicated less pitting corrosion behaviour [18][19].…”

“…Pitting potential (E pit ) was defined as the potential at which current density began to increase continuously 25 . Higher the pitting potential better will be the resistance of the material to pitting corrosion 26 . The susceptibility to intergranular corrosion of cladding was evaluated using the double loop electrochemical potentiokinetic reactivation (DLEPR) tests, following ASTM G108 -94 27 standards.…”

Cladding process can be used to create corrosion resistant surfaces from low cost materials. Austenitic stainless steel has been extensively used for weld cladding. It has excellent corrosion resistance and good weldability. In this context, experiments were conducted by depositing AWS E316LT1-1/4 stainless steel on to AISI 1020 carbon steel and the effects of flux cored arc welding (FCAW) process parameters on pitting and intergranular corrosion was investigated. Response surface methodology (RSM) based central composite design (CDD) was used to predict and develop the mathematical models for process parameters on corrosion resistance. The responses of interest were obtained by double loop electrochemical potentiokinetic reactivation (DLEPR) and potentiodynamic polarization tests. The process parameters analyzed were the wire feed rate, welding voltage, welding speed and nozzle to plate distance. All RSM models developed were statistically significant and presented good adjustments. The results indicated that the process parameters are important in determining the degree of sensitization and pitting potential, and the interaction between parameters cannot be neglected.

“…In agreement with Chen and Szklarska-Smialowska [24] the presence of borides (found on CD04) facilitates pitting initiation and growing since these regions become active anodic points in the presence of chloride ions. Siva and Murugan [5] evaluated the effects of PTA welding parameters on pitting corrosion resistance of an AISI 316L stainless steel and concluded that the increase in current and, consequently, in heat input, reduces the pitting potential. These conclusions are very similar to that observed for samples HI110 and HI133, which represents the lower and higher heat inputs from this work.…”

“…Several processes are used to a produce weld overlay in nickel-based alloys, such as GMAW [1], GTAW [2], and explosion welding [3], as well as PTA [4]. The main advantage of the latter is its higher deposition rate linked to a lower heat input [5], achieving chemical composition and properties more similar to the filler metal than the substrate with only a single pass performed, reducing material and operation costs. As the chemical dilution is reduced, the iron from the substrate that migrates into the overlay is minimised and consequently the reinforcement pitting corrosion resistance is increased.…”

This study aims to evaluate the influence of heat input and dilution on the corrosion behaviour of a weld overlay coating of Inconel 625 deposited using a plasma transferred arc process. Cyclic potentiodynamic polarisation, double-loop electrochemical potentiometric reactivation and critical pitting temperature (CPT) experiments were performed to determine sensitisation and pitting corrosion resistance of the coating, besides microstructural characterisation and microhardness testing. The overlay showed to be resistant to sensitisation in all cases. Within the scope of this study, only the CPT test was able to cause pitting in the alloy, which showed that increments of the specimen's chemical dilution and heat input induced a lower CPT. This is mainly due to different chemical compositions among the distinct phases present in the coating.
