“…Additives such as oxidation inhibitors, high-pressure additives, and nanoparticles can be used to improve the mechanical and tribological properties of lubricants. The use of nanoparticles as friction-reducing and anti-wear additives [22] is of great interest in tribology [20,[23][24][25]. Using a ball-on-disc tribometer under loads of 7 and 10 N, Sanchez-Lopez et al [23] studied the effects of the addition of Pd and Au nanoparticles (5 wt.%) with spherical diameters of approximately 2.2 nm as antiwear lubricant additives on the friction and wear behavior between an AISI M2 steel disc and a 6-mm-diameter AISI 52 100 steel ball.…”

H13 hot work tool steels are subject to high wear and surface deformation. For this reason, it is important to coat H13 steels and to protect the surface forms with lubricants that can be used in the working environment. This study aimed to increase the wear resistance of H13 hot work tool steel by boronizing and to use nano-silver-doped lubricants under working conditions. The boronizing process was carried out at 700, 800, and 900 °C for 2, 4, and 8 h in a nano-boron powder atmosphere. Wear tests were conducted under dry conditions and with nano-silver-doped colloidal suspension prepared with three different ligands. Analyses of the experimental results examined the parameters of friction coefficient, weight loss, microhardness and surface roughness. Ultra-violet (UV), transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy-dispersive x-ray (EDX) spectroscopy, x-ray diffraction (XRD) and 3D topography methods were used for visual and elemental analysis of the surfaces. According to the experimental results, an average coating thickness of 26.5 μm and hardness value of 2001 HV were obtained under conditions of 900 °C for 4 h. The nano-silver-doped colloidal suspension prepared with gelatin yielded 52% better friction coefficient, 88% better weight loss and 51.42% better surface roughness results than the dry wear conditions. It was determined that nano-silver-doped colloidal suspensions prepared with different ligands exhibited different characteristics in the wear environment.

The article presents the results of the investigations on the development of new method of hardening and reconditioning of resource-determining parts of hydraulics aggregates of various purpose machinery by composite electroless nickel coatings. It is proved, that by obtaining the composite chemical coatings the most efficient are nanodispersed particles of aluminum oxide and potassium polytitanate. The tribological testing testified, that the wear of the samples which were deposited with the nickel based composite coating, is 1.4 times less than the wear of the samples with the base nickel coating. The bench testing determined that in spool and sleeves of the hydraulic distributors hardened by the composite electroless nickel deposition, leakage value is 1.4 times less than in commercial ones, and 1.3 times less compared with the pairs being reconditioned by ironing.

Electroplating is the coating metals with thin layers of other metals by electrolysis to improve the surface properties of materials, especially corrosion resistance. Electroplating is widely used in the automotive, electronics, medical, aerospace, gas, and oil industries. This study will discuss the effect of substrate surface roughness of AISI 1045 steel toward surface roughness, hardness, corrosion rate, and bonding strength of the coating. The surface roughness of the substrate is obtained by grinding process using sandpaper with grades 80, 320, and 1000. In this study, the coating material is Chromium. The electroplating parameters used in this research are 5-volt voltage, current 500 Amperes, and the time of 15 minutes. From this research, it is known that the surface roughness of the substrate material has an influence on the quality of the coating. The lower the surface roughness, improve the roughness, hardness, corrosion rate, and bonding strength.
