“…The abrasive wear caused new surfaces accelerate oxidation, and the combined effect of oxidative wear and abrasive wear accelerated the loss of nitrided layer [23]. Therefore, the profile depth at 600°C was the largest, and the surface of worn track was rougher than that at 400°C, which increased the COF [24]. There were obvious parallel furrows, indicating that the abrasive wear occurred on the worn track.…”

A nitrided layer was prepared on H13 mould steel by plasma nitriding. The characteristics of obtained nitrided layer were analysed using an ultra-depth of field microscope, atomic force microscope and X-ray diffraction, and the effect of elevated temperature on the wear performance was investigated using a ball-on-disk wear tester. The results show that the nitrided layer is composed of ϵ-Fe2-3N and γ′-Fe4N phases, which increases the substrate hardness by 111%. The nitrided layer at 800° exhibits superior friction reduction and wear resistance, and the wear mechanism is oxidative wear, which is contributed to the wear-resistant protective layer on the worn track.

“…For a die/mold with high precision requirement, the high-temperature process should be avoided. Whereas other surface treatments, their limitations also are apparent, for example, the unavoidable pores formed during laser cladding can negatively impact corrosion resistance [9,10]; the operation cost of physical/chemical vapour deposition (PVD/ CVD) is high [11]. Consequently, the demand for alternative treatment is increasing.…”

“…This leads to a decrease in durability and service lifetime [1–4]. To date, the most effective method to protect H13 steel is surface engineering such as thermochemical treatment [5–8], laser cladding [9,10], physical/chemical vapour deposition (PVD/CVD) [11], and thermal spraying [12], of which thermochemical treatment can form a compound or diffusion layer with high hardness to improve wear resistance [5,6]. However, the corrosion resistance could not be improved significantly [7,8].…”

The influence of silane pretreatment with five different volume ratios (100/0, 75/25, 50/50, 25/ 75, and 0/100) of 3-aminopropyltriethoxysilane (APTES)/tetraethylorthosilicate (TEOS) on microstructure and corrosion resistance of the hydrothermal synthesized zeolite coatings on the H13 steel substrates was investigated. The surface of the zeolite coatings on the 100/0, 75/25, and 50/50 mixture of the APTES/TEOS pretreated substrates was composed of intergrown rectangular particles. Additionally, pores were observed. A 25/75 mixture of APTES/TEOS pretreatment smoothed the edges and angles of zeolite particles with gel-like materials filled in the pores. In pure TEOS pretreatment, microcracks, and much gel-like materials were observed on the zeolite coating. The electrochemical test revealed that the zeolite coating on a 50/50 mixture of the APTES/TEOS pretreated substrate exhibited the highest corrosion resistance in 3.5 wt-% NaCl solution. This was because a 50/50 mixture of APTES/TEOS pretreatment advantageously promoted development of a dense and thick gel layer, which enhanced the intergrowth of zeolite particles.

The purpose of material selection and surface treatment for a given component is to assure the weapon's failure-free and dependable operation throughout its life time. At the same time, the material and surface technology chosen must take into account the chosen manufacturing method in terms of material attributes, as well as the economics and ecology of production. A gas piston is one of the most visible parts of high-performance small weapons (automatic rifles) that provides its own drive (automation of the functional cycle). The pressure and temperature of the propellant gases, as well as dynamic shocks and wear, put a lot of strain on the gas piston, which puts a lot of strain on the piston material. Steel C55, 80Mn4, 31NiCr14, 42CrMo4, X30Cr13, and X30WCrV9.3 are the most common materials for gas pistons, which are hard chrome plated. Hard chromium plating, which is extremely damaging to the environment and human health, is currently being replaced by PVD or CVD methods. PVD coating deposition processes, for example, have shown to be viable options. Surface treatments including the application of layers and subsequent deposition of coatings are one option (duplex system). The article discusses the use of CrN coating to replace hard chromium plating and the duplex system plasma nitriding + CrN coating (hence PN + CrN). For testing, 42CrMo4 steel was chosen. The strong chrome coating as well as the CrN coating itself were compared to the PN + CrN duplex system. The mechanical and tribological properties, as well as the shape and texture of the surface, were all examined. For exposed sections of small weapons, the PN + CrN duplex system has proven to be a viable alternative to hard chrome coating.
