“…This causes the temperature of torches and especially the contact runner or wire guide, which is in direct contact with the arc plasma, rise to significantly high temperatures and thus accelerates their wear rates tremendously (Kou, 2002;Adam et al, 2001;Shimizu et al, 2006). By coating the wire guide surface using the electro-spark method with the intermetallic materials, the amount of wear was highly reduced and the adhesion of metal droplets to the wire guide surface by splashing was also prevented to a large extent (Yazar et al, 2022). As in many mechanical systems with moving parts, such as machine, wear is the prime cause that leads to the operational failure.…”

Gas metal arc welding is one of the most widely used welding methods in the industry. Especially when large volume welded manufacturing is required, this method is very successful and practical. The wear of the contact guides, which guide the wire at the tip of the welding torches, but most importantly, provide electrical current transmission, may cause the production time to be extended and the calibration period to be minimized. In this study, the most worn part of the contact guides used in the Gas Welding robots were assembled by making pins from doped and undoped copper powders using the powder metallurgy method. The wear performance was compared by making the obtained pin driven contact guides under mass production conditions. In the study, pressing and sintering processes were carried out with Cu and Cu+W powders. The hardness of the contact guides was characterized by their microstructure and XRD results. It was observed that CuW5 and CuW10 powder mixtures were more successful.

Mg alloys are preferred in automotive, aircraft, aerospace and communication industries due to their low specific gravity and high strength. WE series is a series of Mg alloys containing Mg, Y, Nd, rare earth elements, and although the creep strength is good for this alloy series, the wear resistance is open to improvement. The aim of this study is to develop coatings that can increase the wear resistance of WE43 Mg alloys, which have a high potential for use due to their specific gravity, by using a method that can be easily applied in the industry. For this purpose, using the cold spray coating method, magnesium alloys, whose surfaces are highly active, are provided to be coated without oxidation and wear resistance is improved. In the study carried out, WE43 Mg alloys, which roughen the surfaces by fine sandblasting process, were used with cold spray method, using powders containing Al/Zn/Al2O3 and Zn/Al2O3 and trade names DYMET K-20-11 and DYMET K-00-11, respectively, using N2 shielding gas at 500ºC. 6 g/min for powders delivered to supersonic speeds under the atmosphere. The powder was sprayed onto the substrates using the feed rate. Morphological analysis of the coated and uncoated samples with different contents were examined by SEM, XRD methods, the coating thicknesses were measured with SEM images taken from the section, and the percentages of the elements were determined by EDS analysis. In addition, ball-on disc wear tests were performed to examine the wear performance and volume losses were evaluated. As a result, the wear loss of WE43 alloys was reduced by approximately 40% compared to the uncoated condition, thanks to the cold spray coatings.
