“…Besides, it allows the production of small, functional, incompatible, difficult-to-manufacture parts with low dimensional tolerance [3], so it is possible to fabricate parts that are ready for direct usage. Also, it is possible to prepare various steel alloys and modify the chemical composition of the materials with precision [4,5]. Therefore, P/M steels have been utilized to fabricate structural parts in the mechanical fields and automotive industry [6].…”

Developments in sintering of powder mixtures contributed growth of steel production via powder metallurgy. This study aims to improve the mechanical and tribological properties of carbon steels produced via powder metallurgy. For this purpose, P/M carbon steel was alloyed with 3 % Manganese. Then, this alloyed steel was reinforced with particles such as titanium carbide (TiC), titanium nitride (TiN) and titanium carbonitride (TiCN) in different proportions (0.5 and 1 %) and combinations. The effect of these additives on the mechanical properties of PM steels was determined by conducting tensile and hardness tests. Wear tests were performed to understand the tribological properties of samples. Also, microstructural properties, fracture surfaces, and worn surfaces of samples were examined using a Scanning Electron Microscope. Results show that the hardness and tensile strength of carbon steel increased by nearly 158 % and 62 % respectively, while the wear resistance improved by 4 times with the addition of 3 % Mn and 0.5 % TiCN.

“…So, the active vapor is more effective as the treating time and temperature increase. Therefore, with increasing all the three specific parameters, the diffusion of the silicon inside the substrate improves [22]. The ordinary diffusion of the silicon supports the growth of the silicide layer inside the substrate.…”

The paper describes the pack siliconizing optimization procedure for AISI D2 tool steel. Pack siliconizing was performed by employing different treating temperatures (falling in the range 650–950 °C) and times (falling in the range 2–4 h). The siliconizing atmosphere was obtained through silicon (at 12 wt.%) with the addition of different percentages of NH4Cl (falling in the range 0.5–1 wt.%), Al2O3 was used as halide activator. The coatings’ phases evolution was analyzed through X-ray diffraction; the coatings’ thickness was measured through scanning electron microscopy observations of the cross section of the samples; the mechanical properties were evaluated through micro hardness measurements. The results showed that the coatings’ thickness and hardness increase as the treating time and temperature as well as the halide activator percentage increase. The coating procedure optimization was performed by employing the response surface methodology based on Box-Behnken method. The results of the optimization procedure led to the of the optimal combination of processing parameters: 1 wt.% of halide activator, 3.575 holding time, 950 °C in temperature.

“…The group develops studies considering improving materials' tribological behaviour through surface changes, increasing materials' tribological performance, especially in parts produced by powder metallurgy [333,[358][359][360][361][362][363][364]. The group has been developing niobium-based tool materials (cermets) [365][366][367][368] and zinc-aluminium alloys [369]. Recently, the group started to work on special titanium alloys for biological use.…”

This first regional issue published in STMP highlights the potential and importance of the research carried out in Latin America regarding surface engineering and tribology. In order to celebrate this important initiative, a complete historical account of Brazilian tribology is presented for the first time. It initiates with the first steps of Brazilian tribology in the 1980s, followed by the evolution and expansion of tribology research both in academic centres and industry. Focus is given to two outstanding achievements of Brazilian tribology: the fully flexible engines that run at any proportion of ethanol and gasoline and a fully innovative, completely oil-less family of hermetic compressors. The status-quo of the current research groups on tribology is described. Finally, the future trends envisaged by the Brazilian tribology community are presented.
