“…This effect results from sharp-edge abrasive particles, which penetrated deep into the investigated surface. The effect of penetration is a larger amount of material removal from specimens, which initiated the grooving mechanism [44]. In contrast to the wear mechanism for Hardox 450 steel (grooving), the rolling mechanism was predominant in investigated coatings.…”

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.

“…The length of those cracks was much higher. It was stated in the literature [44] that the presence of the cracks influencesa lower abrasive wear resistance of performed coatings. The exemplary results of metallographic microscopic tests are presented in Figure 9.…”

“…Another study about the effect of deep cryogenic treatment which was published by Özer, concluded that there is no significant difference between conventionally heat-treated and deep cryo treated samples [22]. Singh et al performed five different thermal treatment procedures to 30MnCrB4 steel [23]. The first one conventionally heat-treated, the second one conventionally heat-treated and deep cryo treated at 185 °C for 12 h and the last three group of samples were subjected to conventionally heat treated, deep cryo treated and tempered at 200 °C, 250 °C and 300°C for 1 h, respectively.…”

“…At 2000× magnification along with dimple structure, flat regions were observed suggesting mixed mode of fracture (Figure 14c). [25] stated that tempered post cryogenic treatment of boron steel on post tempering resulted in grain coarsening and martensite decomposition with bubble and dimples coalescence along the grain boundaries. The fracture surfaces exhibited a mixed morphology with micro voids and elongated dimples which are characteristic representation of ductile fracture.…”

Digital Image Correlation of Tensile Properties for Monel 400/SS 316L Dissimilar Metal Welding Joints

et al. 2021

Dissimilar metal weld joints of Monel 400 and Stainless Steel 316L stainless steel were carried out using Gas Tungsten Arc Welding (GTAW). Conventional annealing and cryogenic treatment were performed on the welded joints. Weld joints of this combination of materials have enormous potential applications in power industry and the available related literature is limited. In the present study, the tensile properties of heat treated (HT), cryotreated (CT), and untreated (UT) specimens were studied. The engineering stress and strain were determined experimentally as per Standard Test Methods for Tension Testing of Metallic Materials (ASTM E8). The strain distribution was evaluated at different zones of weld joint was evaluated using Digital Image Correlation (DIC). Significant difference was noticed between the zones. Weld zone of all samples had less local stress and strain and SS 316L heat affected zone (HAZ) zone had more local stress and strain when compared to other zones. The local strain distribution along distance from weld center line and local stress-strain curves of different zones are also predicted. Scanning Electron Microscopy was used to analyze the fracture behavior of welded samples for HT, CT, and UT specimens.
