Abstract
Mechanical components, especially moving parts, suffer from wear as a result of the high contact pressures and temperatures. To reduce such damage, it is common practice the use of coatings, since the high contact pressures and temperatures and consequently wear mostly occur at the surface. Inconel 625 is widely used in the petroleum industry in the form of thick coatings. It consists of a nickel and chrome superalloy, highly resistant to corrosion, besides presenting high mechanical resistance at high temperatures. However, the use of Inconel 625 in the petrochemical industry also requires that it presents high abrasion resistance due to the possible presence of sand particles in moving contacts. This study used a single pass pendular to evaluate the scratch resistance of Inconel 625 deposits onto carbon steel substrates. In particular, it was evaluated the effect of the variation of the shielding gas composition during deposition of Inconel 625 by gas metal arc welding (GMAW).
