Summary: This study investigates the influence of surface preparation of hardened AISI D2 steel substrate on the adhesion characteristics of an AlCrN coating. It was found that using cermet cutting inserts in the milling process led to higher compressive residual stresses and lower roughness values, increasing the critical load required for coating failure. Although scratch tests showed sensitivity to differentiate substrate surface properties, indentation tests were not successful in this regard.

Summary: This study conducted a comprehensive experimental investigation on the wear behavior of coated spur polymer gears made of POM. The results showed that the metallization of aluminium coatings did not significantly affect the wear behavior of the analysed polymer gear. Additionally, gears with thicker aluminium coatings exhibited greater wear compared to gears with thinner coatings or without coatings.

Summary: Recently, the focus of research on electric arc-based welding techniques has been on the changes in microstructure and mechanical properties of repaired materials and components. This study investigated the effects of a thermochemical treatment, boriding, on a low carbon steel repaired by arc welding. Micro-abrasion tests were conducted to evaluate the tribological behavior of the repaired steel before and after boriding. The results showed that boriding treatment effectively increased the hardness and wear resistance of the repaired steel without creating gradients between the original material and the repaired zone.

Summary: AISI 316L stainless steel is widely used in various industries due to its high tensile and rupture strength at different temperatures. However, the wear debris and oxide products may lead to detrimental effects in medical applications, causing issues like aseptic implant loosening and demineralization of bone tissue. Research has been focused on improving the tribological performance of steel surfaces, including the study of boride layers as a means to enhance corrosion resistance and reduce wear rates.

Summary: High Speed Steel (HSS) specimens were coated with AlCrN and AlTiN using the PVD method for micro-abrasion wear behavior testing. It was observed that increasing the particle size of SiC and Al2O3 abrasives led to higher wear loss, with AlCrN coatings showing better wear resistance compared to AlTiN.

Summary: This study aimed to investigate the microstructure of borided cases on AISI/SAE 4140 steel by varying the boron content in the pack boriding powder mixture. Different amounts of B4C were employed, resulting in boron contents of 1.21, 4.35, and 8.26 wt.% in the pack boriding powder mixtures. The boriding process was conducted at 900°C for 1, 2, and 4 hours. The microstructure was characterized using scanning electron microscopy and x-ray diffraction, while mechanical properties were evaluated through instrumented indentation. Adhesion strength and failure modes of the borided layers were determined by scratch testing, and tribological properties were examined through ball-on-disc sliding wear tests. The results showed that a lower boron content (1.21 wt.%) produced borided cases with only Fe2B layer, whereas a higher boron content (8.26 wt.%) resulted in borided cases composed of Fe2B/FeB phases. The Fe2B/FeB borided layer exhibited high hardness, and the highest wear rate was observed in the specimen with the highest boron content for 4 hours.

Summary: The reciprocating sliding wear tests were conducted on TiAlN coating against 316L stainless steel and carbide-free bainitic steel at temperatures of 40, 400 and 800 degrees C. The results showed that material transfer was more significant for the softer stainless steel at lower temperatures, while carbide-free bainite exhibited more material transfer at 800 degrees C. Friction coefficient increased for stainless steel with increasing temperature, but decreased for carbide-free bainite at elevated temperatures due to the formation of an easily sheared iron oxide layer. Additionally, the generation of a thin tribofilm containing aluminium oxide and oxidised transferred material could protect the TiAlN coating against wear at 800 degrees C in the case of stainless steel.

Summary: This research work focuses on developing and comparing in-house Ti-based coatings with commercial coatings for cermet tools used in high-speed dry turning of Austenitic stainless steel. By evaluating and comparing the performance of commercial coatings on cermet tools based on micro-mechanical properties, tool performance, and surface roughness, the study found that in-house Ti-based coatings with similar compositions to commercial coatings performed better, depending on their micro-mechanical properties. Research results indicate that the compositions of various coatings significantly influence the micromechanical properties and tool life.

Summary: This study investigated the adhesion properties and wear behavior of AISI 4140 and borided AISI 4140 steels. The results showed that the presence of a single-phase Fe2B layer on the surface of AISI 4140 steel increased its wear resistance by about 20 times.

Summary: Refractory metal based alloys have great potential as structural materials for high-temperature applications due to their high melting points. However, they are prone to catastrophic oxidation at around 700 degrees C. This study investigated the effect of aluminium diffusion coatings on the oxidation resistance of pure molybdenum, niobium, tantalum, and tungsten. The results showed that the aluminization improved the oxidation behavior and decreased the oxide growth rate for molybdenum and tantalum.
