“…Thermochemical heat treatments such as carbonitriding, carburizing and boronizing are widely used to improve surface properties of ferrous material for increasing their wear, corrosion and fatigue performance [3]. Depending on the boronizing/carburizing source, time, temperature, and chemical composition of substrate, the boride and/or carbide, and niobium carbide layer forms on the substrate and its depth changes with these parameters [13].…”

In this study, the hardness and wear behaviour of carburized and boronized AISI 8620 steels have been studied. The boronizing treatment increased the hardness of AISI 8620 steels from 395 HV0.1 to a maximal 1610 HV0.1 compared to the carburized steels and also significantly improved its wear behaviour. From obtained results, it can be concluded that boronizing is very effective surface hardening method for improving the wear properties of AISI 8620 steels.

“…Electroplated nickel coating, codepositing silicon (Ni-SiC) has been the coating of choice for in-cylinder applications because of its hard wearing and relatively low friction characteristics, particularly for high performance engines as reported by Howell-Smith et al 10 and Mistry et al 16 Another recent development has been boriding with favourable wear characteristics. Furthermore, borided steel yields a lower coefficient of friction in sliding contacts than the parent steel substrate, 17 especially after a short annealing process. 18,19 Recent developments in the boriding process have reduced the fabrication times to around 15 min, 20,21 with significant inservice improvement at elevated temperatures, which has resulted in commercially viable borided engine cylinders.…”

Frictional losses are one of the main causes of reduced energy efficiency in all machines and mechanisms. In particular, there is mounting pressure upon manufacturers of all forms of vehicle to comply with increasingly stringent legislation and directives with regard to harmful emissions. Therefore, reduction of friction has become an imperative issue. The traditional approach of dealing with surface material and lubricant formulation in isolation has been replaced by a lubricant-surface system approach. This paper presents multi-scale experimentation from nano/meso-scale lateral force microscopy of ultra-thin surface adsorbed films through to micro-scale precision sliding tribometry to investigate lubricant-surface friction optimisation within the mixed regime of lubrication, using lubricants with different organic and inorganic friction modifying species. These affect the parameters of the system, commonly used as input to models for mixed and boundary regimes of lubrication. Therefore, the precise measurement of these parameters at different physical scales is important. The study also makes use of detailed numerical predictions at micro-scale through combined solution of the average Reynolds equation as well as interaction of wetted asperities in mixed and boundary regimes of lubrication. Good agreement is found between the predictions and measurements at micro-scale tribometric interactions. Furthermore, the same trends are observed in testing across the physical scales.

“…1,2) Boriding is divided into pack boriding, liquid boriding, and gas boriding. Among these, the pack boriding, a process similar to pack carburizing, is mostly applied and studied at the present time because of its technical advantages, including ease of treatment, ability to achieve a smooth surface, and simplicity of required equipment.…”

The present study evaluate the catalysis of Nd2O3 on the boriding of AISI 1045 steel using a 5% Nd2O3-containing boriding agent in a temperature range of 1 213 K to 1 350 K for 2 h-5 h. The morphology and types of borides formed on the steel surface were confirmed by optical microstructure, scanning electron microscopy and X-ray diffraction. The results show that the Nd2O3 has contrary effects on boriding process, i.e. promotion at high temperatures or hindrance at low temperatures. Nd2O3 addition can significantly reduce the activation energy of boride growth at high temperatures, decreased it from 198 kJ/mol to 137 kJ/mol, reduced by 31% in the high temperature range of 1 133 K-1 213 K as compared with that without Nd2O3 addition. The catalysis mechanism of RE element Nd during boriding process was discussed through the analysis of chemical reactions probably occurred in boriding agent, changes in surface morphology and chemical composition.
