“…It was established that the level of alloying results in different final structure of the steel (ferrite-bainite, bainite, or martensite-bainite), for which the proper thermal and deformational treatment must be selected to initiate phase transformation and matrix strengthening. Alloying by C and Mn leads to hardness increase in steels due to the effect of solid solution strengthening, as it was determined in [16].…”

Industry and our daily life place high demands on construction materials, among which steels are the most prospective. Particularly, agricultural machinery greatly depends on high quality steels for more reliable and efficient machines. So, the development of advanced steels is an important task for material science. The present paper concerns the complex analytic and experimental study of the processes at crystallization and recrystallization in solid of alloyed structural steels, containing up to 0.4 wt.% C, 2% Si, Mn and Cr, 0.035% N, 0.3% V and their relation to mechanical and operational properties. The processing of steels was undertaken at melting in an induction furnace, including varying Si, Mn, Cr content and alloying by V and N, subsequent deoxidation by SiCa and Al. Different thermal treatment of the samples was applied, including quenching, hardening, tempering, normalization. The analysis of the established regularities allowed realizing in practice proper steel processing and providing an increased level of steel strength without reducing in plasticity. It was determined that the tensile strength of the steels was increased with increment of 80-120 MPa after normalization and of 200-250 MPa in quenched and tempered state, whereas the fatigue limit was increased by 100-120 MPa. The part of the tractor made of the processed alloy steel has shown better performance and wear resistance than commonly used carbon steel proving the effect of alloying and thermal treatment.

“…HSLA steels are widely applied in nuclear fission power plant components, pipeline operators, navy vessels, petrochemical industries, the automotive sector etc. [10–13]. DH-36 is a HSLA naval-grade steel which is frequently used for the construction of ships and offshore structures due to its property to withstand sub-zero temperatures.…”

The aim of this work was to investigate the flexural strength and corrosion behaviour of graphene-reinforced WC-10Co-4Cr HVOF coating on sandblasted and laser-textured DH-36 naval-grade steel. In this regard, WC-10Co-4Cr and WC-10Co-4Cr + 3% graphene nanoparticles (GNPs) are applied on DH-36 substrates using the HVOF coating technique and their microhardness, flexural strength and corrosion behaviour are investigated. Amongst all, the flexural strength of WC-10Co-4Cr + 3%GNPs coating on laser-textured sample with pitch-to-diameter (p/d) ratio 2 was minimum (327.006 MPa) due to the effect of GNPs and better mechanical interlocking at the coating-substrate interface. Also, the corrosion resistance of coated DH-36 steel was evaluated by salt spray test; it revealed that corrosion resistance was improved with the application of WC-10Co-4Cr coating, which was further enhanced by the addition of GNPs as GNP has the property of being impermeable to gasses and salts. Further, microstructures and morphologies of the corroded surface were investigated using FE-SEM images.

“…Surface modification techniques, such as laser texturing and the application of low-friction coatings, have shown promise in enhancing the performance of protective coatings against slurry erosion [12][13][14][15]. Laser surface texturing involves creating micro-scale patterns on the coating surface, altering hydrodynamic conditions and influencing the behaviour of slurry particles [16][17][18].…”

This research explores the enhanced slurry erosion behaviour of a composite coating comprising Titanium Carbide (TiC) deposited via High Velocity Oxy-Fuel (HVOF) spraying process. The study integrates laser texturing and Polytetrafluoroethylene (PTFE) spraying techniques to improve the coating's performance. TiC coating is applied to SS316 substrates using HVOF, followed by laser surface texturing to create micro-scale circular patterns. A thin layer of PTFE is then sprayed onto the textured surface, enhancing static contact angle and anti-adhesive properties. Slurry erosion tests reveal significant improvements in the coating's resistance. The findings offer promising applications in slurry erosion-prone industries. Further investigations aim to study the erosive mechanism of the different samples and evaluate their long-term performance.
