“…The coating thickness on the grinding tool and the removal amount of the diamond film were proportional to the CEPIS grinding time, as reported by Chen et al 11 This indicated that the sharpness of the grinding tool was maintained so that the grinding tool resharpened by a procedure called dressing could be eliminated. The diamond film could be ground using this method with diamond grit size of 10 mm and grinding time of 15 min to achieve a surface roughness that was superior to that using conventional machining.…”

“…8,9 Because the equipment used in mechanical grinding is relatively simple, it is widely used in the polishing of diamond films. Moreover, many modified methods, such as the electronic in-process dressing (ELID) 10 and composite electroplating in-process sharpening (CEPIS), 11 are also used to improve the capability of grinding tools and thus the efficiency of grinding.…”

Finishing mirror-like surfaces on chemically vapor-deposited diamond film using an in-process composite electroplating of diamond grains onto the tool surface, the tool can maintain its sharpness in a grinding process. The effect of diamond grit size of the tool on the grinding characteristics of diamond film is investigated. To promote optimum grinding efficiency, a high variation rate in the surface roughness of diamond film and a small growth rate in the coating thickness are desired. A distribution model of the diamond grits in the coating layer is deduced, and a composite electroplating in-process sharpening grinding mechanism is developed using a body-centered tetragonal structure. A two-stage composite electroplating in-process sharpening grinding procedure is used to grind the diamond film. A grit size of 25 µm is selected to conduct the composite electroplating in-process sharpening grinding for 30 min at an initial surface roughness of 1.1 µm. Then, the operating conditions are switched to a grit size of 3 µm and a grinding time of 180 min, and a mirror-like surface on the diamond film with an average surface roughness of 0.03 µm is obtained.

In order to improve the performance of electrodeposited diamond-nickel composite, surface modification of diamond particles was carried out using powder immersion reaction assisted coating (PIRAC). Titanium and chromium were selected as coating elements, which are known as carbide former. With respect to the powder elements, various phases were formed on diamond; metallic Ti and TiC for Ti powder, Cr 3 C 2 for Cr powder, and TiC and Cr 3 C 2 for Ti-Cr mixed powder. Surface modified diamond particle showed higher specific surface area, especially Ti coating induced considerable increase of specific surface area. The increase of specific surface area suggests increase of surface roughness, and that was confirmed by surface observation using FE-SEM. In addition, wear properties of diamond-nickel composite including surface modified diamonds were improved, and Ti coated diamond showed the highest performance. The wear property of diamondnickel composite is dependent on adhesion strength between diamond particle and nickel layer. Therefore, surface modification of diamond particle by PIRAC increasing surface roughness is effective to improve the properties of diamond-nickel composite.

“…DLC coatings are generally deposited on the materials' surface using electro-plating, laser coating [11], pulsed electrode plating, thermal spraying [12], chemical vapor deposition (CVD), physical vapor deposition (PVD) [13][14][15], electron bombardment, and evaporator [12,[16][17][18] methods. Their resistances according to temperature, friction, wear, and corrosion effects depend on the variety of coating methods and coating parameters [18][19][20].…”

Analysis of Tribo-corrosion Properties of MAO/DLC Coatings Using a Duplex Process on Ti6Al4V Alloys

In recent years, various technologies have been increasingly investigated for the surface modification of Ti and Ti alloys. Microarc oxidation (MAO) is one of the effective techniques to improve surface properties. However, it has some disadvantages for sliding wear applications and/or aggressive environments. In this study, the combined MAO and closed field unbalanced magnetron sputtering process was used to deposit duplex MAO/diamond-like carbon (DLC) coatings on Ti 6 Al 4 V alloy. Analysis of the microstructures, morphology, and crystallographic structure were performed by using a SEM, Raman, and XRD. The wear, corrosion, and tribo-corrosion properties of the coatings were investigated using the pinon-disk wear test, potentiodynamic polarization test, and combining tribo-corrosion test unit, respectively. The results of this study have shown that duplex MAO/DLC coatings exhibit better wear, corrosion, and tribo-corrosion properties than the DLC or MAO monolayer on Ti 6 Al 4 V alloy substrate. MAO/DLC coatings exhibited dense structure, lower coefficient of friction and corrosion current density, and higher tribo-corrosion resistance. The results have also shown that MAO/DLC duplex coatings on Ti 6-Al 4 V substrates increased the tribo-corrosion resistance by acting as a barrier layer.
