“…It was observed that the wear resistance and micro-hardness property of the coating were enhanced due to the presence of C 3 N 4 , B 13 C 2 , and TiCN phases. Ren et al [11] fabricated anti-wear composite coating on titanium alloy and found the formation of some phases like TiC, TiWC 2 , CrS, Ti 2 CS, etc., which owing friction-reducing effect.…”

The Ti6Al4V is widely used in harsh working conditions where wear and tear are the common phenomena. In order to enhance its performance and life, the laser cladding took place using Ti6Al4V:WS 2 : Ni as the reinforcement material. The influence of scanning speed on mechanical and tribological properties like hardness, wear resistance, and microstructure of the cladding parts is discussed. The dendritic, white, and grey phased fine microstructures are observed. The micro-hardness of the clad is increased up to four times (∼1170 HV 0.5 ) of the substrate material due to the formation of a hard Ni-Ti phase. The wear resistance of the clad is exhibited two times higher than that of the substrate. Also, the coefficient of friction is reduced to 0.25 as the adhesion wear mechanism becomes predominant over the abrasion.

“…Many investigations [32][33][34][35] revealed that erosion resistance is very much influenced by the impingement angle, particle characteristics and morphological features, coating hardness and microstructure, involvement of high temperature adopted during erosion tests. Researchers have worked on Cr 3 C 2 -25NiCr and WC-NiCrBSiFe-based coatings on SS steels for room temperature conditions.…”

This work concerns a technique to produce thermal sprayed coatings using HVOF (highvelocity oxy-fuel) method as it is a widely used application in high-temperature erosion and corrosion environment. Two types of hard coatings Cr 3 C 2 -25NiCr and 35WC-Co/65NiCrBSi were sprayed on an SS-347 steel substrate. The erosion tests were done using hightemperature jet erosion set up to study the effect of velocity, temperature and impact angles on the coatings produced. The surface morphology of the samples was characterized using 3D laser confocal microscopy, light microscopy, scanning electron microscopy with EDAX and X-ray diffraction. Microhardness, porosity level and roughness parameters were evaluated to infer a probable mechanism of material removal. The Cr 3 C 2 -25NiCr coating exhibited ∼3.3 times higher erosion resistance than 35WC-Co/65NiCrBSi coating at 90°and 30°impact angles. SEM and 3D laser confocal images on the eroded surface of the coatings reveal the combination of ductile and brittle fracture of coating.

“…Feng et al [21] indicated that the cutting force and cutting temperature could be significantly reduced when a textured tool was used. As a conclusion, the textures on the tool surface can effectively reduce the tool-chip contact surface, reduce cutting temperature and cutting force, store lubricant, improve the contact state, and decrease the adhesion phenomenon [22][23][24][25]. However, the effect of sinusoidal textures and rhombic micro textures of tools on the cutting performance of titanium alloy is still unclear, which is necessary to be studied to further improve the cutting efficiency and surface quality of titanium alloy.…”

Titanium alloys are widely used in various fields, but their machinability is poor because the chip would easily adhere to the tool surface during cutting, causing poor surface quality and tool wear. To improve the cutting performance of titanium alloy Ti-6Al-4V, experiments were conducted to investigate the effect of micro textured tool on the cutting performances. The cemented carbide tools whose rake faces were machined with line, rhombic, and sinusoidal groove textures with 10% area occupancy rates were adopted as the cutting tools. The effects of cutting depth and cutting speed on feed force and main cutting force were discussed based on experimental results. The results show that the cutting force produced by textured tools is less than that produced by non-textured tools. Under different cutting parameters, the best cutting performance can be obtained by using sinusoidal textured tools among the four types of tools. The wear of micro textured tools is significantly lower than that of non-textured tools, due to a continuous lubrication film between the chip and the rake face of the tool that can be produced because the micro texture can store and replenish lubricant. The surface roughness obtained using the textured tool is better than that using the non-textured tool. The surface roughness Ra can be reduced by 35.89% when using sinusoidal textured tools. This study is helpful for further improving the cutting performance of cemented carbide tools on titanium alloy and prolonging tool life.
