In this paper, the effects of different hydrophobic coatings on the surface of covered electrodes on the quality of wet welded carbon steel joints were discussed. Commonly available hydrophobic substances used in industrial applications were selected for the research. The aim of using waterproof coatings was to check the possibility to decreasing the susceptibility of high-strength low-alloy S460N steel to cold cracking. During experiments diffusible hydrogen content in deposited metal determination by mercury method, metallographic macro- and microscopic testing and hardness measurements were performed. Investigations showed that waterproof coatings laid on covered electrodes can improve the quality of wet welded joints, by decreasing the Vickers HV10 hardness in heat-affected zone and decreasing the diffusible hydrogen content in deposited metal, which minimalize possibility of cold cracking.

The Abrasive Wear Resistance of Coatings Manufactured on High-Strength Low-Alloy (HSLA) Offshore Steel in Wet Welding Conditions

Some marine and offshore structure elements exploited in the water cannot be brought to the surface of the water as this will generate high costs, and for this reason, they require in-situ repairs. One of the repair techniques used in underwater pad welding conditions is a wet welding method. This paper presents an investigation of the abrasive wear resistance of coatings made in wet welding conditions with the use of two grades of covered electrodes—an electrode for underwater welding and a commercial general use electrode. Both electrodes were also used for manufacturing coatings in the air, which has been also tested. The Vickers HV10 hardness measurements are performed to demonstrate the correlation in abrasive wear resistance and the hardness of each specimen. The microscopic testing was performed. For both filler materials, the coatings prepared in a water environment are characterized by higher resistance to metal–mineral abrasion than coatings prepared in an air environment—0.61 vs. 0.44 for commercial usage electrode and 0.67 vs. 0.60 for underwater welding. We also proved that in the water, the abrasive wear was greater for specimens welded by the general use electrode, which results in a higher hardness of the layer surface. In the air welding conditions, the layer welded by the electrode for use in the water was characterized by a lower hardness and higher resistance to metal–mineral abrasion. The microstructure of the prepared layers is different for both the environment and both electrodes, which results in abrasive wear resistance.

“…Investigation into the wear resistance of ferrous alloys is still an important problem; consequently, many authors research into the sliding [7,8], abrasion [2,9], erosion [10,11], corrosion [12][13][14] or cavitation erosion [8,15] wear resistance of commercial steels such as S235, S355, C45, AISI 304 and Hardox 500. However, the information about the steel wear properties examined for a wider group of commercial materials is limited.…”

“…Thus, the current work is focused on examining the three carbon steels commonly used in industrial practice: S235 and S355, C45 (popular structural materials) which were compared with classic stainless steel grade X5CrNi18-10 (AISI 304) and with Hardox 500,the low-alloy abrasive-wear resistant steel that is gaining favor [2,[17][18][19][20][21][22]. Therefore, the steel materials investigated in current work are usually used as a reference material in various wear tests [3,15,18,[23][24][25]. Thus, the information presented in our findings seems promising for comparing or evaluating the abrasion wear results reported by the literature, which also enables the transfer of the wear results into fabrication and operation conditions.…”

“…Additionally, the thermal spray technology is applied to deposit the wear resistant coatings e.g. Łatka et al [15] conducted the research on the atmospheric plasma sprayed Al 2 O 3 +13wt.%TiO 2 ceramic coatings on X5CrNi18-10 substrate, in other work HVOF (High Velocity Oxygen Fuel) method was used to spray the M(Ni,Co)CrAlY and Cr 3 C 2 -NiCr composite coatings onto stainless steel [33] or a flame sprayed Ni-and Fe-based coatings fabricated on mild steel and finally PVD or CVD thin films [8,34] were considered for increasing the wear resistance. However, the selection for wear application of commercial steels seems to be still an up-to-date and unsolved problem.…”

The steel presents a wide field of application. The abrasive wear resistance of steel relies mainly on the microstructure, hardness as well as on the abrasive material properties. Moreover, the selection of a abrasion-resistant grade of steel still seems to be a crucial and unsolved problem, especially due to the fact that the actual operating conditions can be affected by the presence of different abrasive materials. The aim of this work was to determine the effect of different abrasive grit materials i.e. garnet, corundum and carborundum on the abrasive wear result of a commonly used in industry practice steels i.e. S235, S355, C45, AISI 304 and Hardox 500. The microstructure of the steel was investigated using light optical microscopy. Moreover, hardness was measured with Vickers hardness tester. Additionally, the size and morphology of the abrasive materials were characterized. The abrasion tests were conducted with the usage of T-07 tribotester (dry sand rubber wheel). The results demonstrate that the hardness and structure of steels and hardness of abrasive grids influenced the wear results. The abrasive wear behavior of steels was dominated by microscratching and microcutting wear mechanisms. The highest mass loss was obtained for garnet, corundum, and carborundum, respectively. The usage of various abrasives results in different abrasion resistance for each tested steel grade. The AISI 304 austenitic stainless steel presents an outstanding abrasive wear resistance while usage of corundum and Hardox 500 while using a garnet as abrasive material. The C45 carbon steel was less resistant than AISI 304 for all three examined abrasives. The lowest resistance to wear in garnet and carborundum was obtained for the S235JR and S355J2 ferritic-perlitic carbon steels and in corundum for Hardox 500 which has tempered martensitic structure.
