Summary: In this study, a hard solid-lubricating clad layer was developed on a Ti-6Al-4V substrate using pre-placed powder TIG cladding technique to improve its mechanical, corrosion, and electrical discharge wear properties. The combination effect of Ti, Ni, and Si coating powders with different percentages of La2O3 in a N2 environment was investigated. The analysis revealed the presence of both hard (NiTi, TiO2, and TiAlN) and solid lubricating (LaNi5 and Si3N4) phases. The sub-surface analysis showed defect-free cladding with strong metallurgical bonds and refined microstructure near the interface. The coated samples exhibited significantly improved mechanical wear, corrosion resistance, and reduced electrical discharge wear, making them suitable for various applications.

Summary: This study investigated the relationship between coating temperature and remelting power using vertically remelted plasma-sprayed NiCrBSi coatings. The remelting process reduced porosity, eliminated lamellar boundaries, and promoted metallurgical bonding in the coatings. However, excessive remelting power may result in coating loss and microstructural coarsening.

Summary: This study focuses on developing a wear-resistant Yttria Stabilized Zirconia (YSZ) reinforced Inconel-625 (IN625) TIG weld composite cladding for the AISI 304 stainless steel substrate. By optimizing the TIG welding current, scanning speed, standoff distance, and YSZ reinforcement percentage, the researchers obtained a fine and dense microstructure, resulting in maximum hardness and minimum wear. The inclusion of YSZ particles in the IN625 matrix led to the formation of stable oxides and gamma-Ni phases. The weight loss in the claddings was primarily due to abrasive wear.

Summary: In this study, a metal matrix composite covering the Ti6Al4V substrate was successfully formed using high-quality reinforcement materials. The effect of process parameters on the clad layer thickness and micro-hardness was investigated using response surface methodology. It was found that laser power and scanning speed significantly influenced these responses. Different compositions of reinforcement materials were characterized on the cladded surfaces. Analyzing the binding energy of these phases through XPS confirmed the formation of metal matrix composites of nitrides and borides as the main constructive phase of the clad. The clad exhibited enhanced hardness and wear resistance properties. However, spalling craters and wear debris were found in cladded samples.

Summary: This study focuses on minimizing the corrosion rate of a copper substrate by electroless deposition of Ni-P alloy. Central composite design and particle swarm optimization were used to analyze and optimize the process parameters. The results showed that the concentration of nickel sulfate, the concentration of sodium hypophosphite, and the bath temperature were the key factors affecting the corrosion rate. The optimal conditions for achieving a corrosion rate of 0.862 mm/Y were found to be 21.59 g/L of nickel sulfate, 26.72 g/L of sodium hypophosphite, and 93.41 degrees Celsius. The analysis also confirmed the significance of the interaction between sodium hypophosphite and bath temperature in determining the corrosion rate. Optical microscopy, scanning electron microscopy, and energy dispersive X-ray analysis were conducted to study the surface morphology and elemental composition of the coated substrate.

Summary: Laser cladding using Ti6Al4V:WS2:Ni as reinforcement material can significantly improve the hardness and wear resistance of the cladded parts. The microstructure of the clad consists of dendritic, white, and grey phases, and the micro-hardness is increased up to four times. The wear resistance is doubled and the coefficient of friction is reduced to 0.25.

Summary: This study examined the effect of processing parameters on the abrasive wear behavior of WC-10Co-4Cr TIG cladding, and found that the cladding obtained at the optimum processing condition exhibited better wear resistance due to the presence of a large number of partially melted WC grains. Improvements in hardness and fracture toughness also contributed to the enhancement of abrasive wear resistance in the optimized TIG cladding.

Summary: A Ta-modified layer was prepared on Ti6Al4V substrate by double-glow plasma surface alloying technique (DGPSAT) at 750 degrees C to improve the corrosion resistance of biomedical titanium alloys. The effects of Ta coating alloying time on microstructure, film cohesion strength, and electrochemical corrosion properties were investigated. The results showed that the sample with an alloying time of 30 minutes exhibited the best cohesion strength and corrosion resistance.

Summary: Wire and arc additive manufacturing (WAAM) is an economic and efficient technology suitable for producing large-scale metallic components, particularly in the fabrication of near-net-shape and large-scale titanium alloys. It has been significantly noticed and adopted due to its high deposition rate, low machinery cost, and shortened lead time compared to other powder-based additive manufacturing techniques.

Summary: Ni60/nickel-coated graphite/TiB2 composite coatings were prepared by laser cladding to improve anti-wear and friction-reducing properties. The increase in TiB2 content led to changes in graphite morphology and higher hardness. Addition of nickel-coated graphite increased hardness, generated TiC and Cr7C3, and improved friction reduction and anti-wear properties.

Summary: The electrical discharge coating process is used to prepare a hard and wear-resistant coating using a green compact tool of Cu+MoS2+WS2+hBN powder. The coating morphologies consist of hard and soft phases, with an increase in coating elements concentration towards the coating surface. The hierarchical rough structure of the coatings results in a super-hydrophobic state, with higher microhardness and lower specific wear rates compared to the substrate.
