Accordingly to the literature of the subject [18,19] the indentation depth (h) was always below 10% of the coating thickness. The hardness and elastic modulus were calculated from the load-displacement data according to the Oliver Pharr method [20].…”

Consideration of thin films such as deposition of TiAlN or AlTiN on DMLS (direct metal laser sintered) titanium-based implants is a new biomedical trend. The present study encompassed the investigations of hardness, Young modulus, adhesion of TiAlN and AlTiN magnetron sputtered coatings deposited on DMLS (direct metal laser sintering) of Ti6Al4V substrate. The titanium based substrate was manufactured in the DSLM process by means of 3D EOSINT M280 printer for metals supplied by EOS. The surface morphology of specimens was examined using the Dektak 150 profilometer (Veeco Instruments Inc., USA). The mechanical properties (hardness, Young's modulus) of nitride coatings and the substrate were tested by means of Ultra Nanoindentation Tester (Anton Paar GmbH, Germany). The values of hardness and elastic modulus were calculated from the load-displacement data according to the Oliver Pharr method. The adhesion of deposited coatings was determined by means of the scratch test and Rockwell test. Scratch tests were performed on a Micro Combi Tester (Anton Paar GmbH, Germany) according to the ASTM C1624 − 05(2015) standard for ceramic coatings scratch testing. It was found that TiAlN as well as AlTiN films were characterised by excellent adhesion to DMLS titanium-based substrate as well as sufficient morphology and mechanical properties.

“…As the thickness of the coatings in the present work is 25 µm, the indentation depth is accordingly estimated to be about 16% of the coating thickness. This may affect the hardness results by introducing the effect of substrate as reported in other research works [44][45][46].The indentation depth is recommended to not exceed 1/10 of the measured coating thickness [44][45][46]. Therefore, for thin coatings, it is always suitable to address nano-hardness instead of micro-hardness, keeping in mind the thickness of the films.…”

Ni-B alloys deposited by the electroless method are considered to be hard variants of the electroless nickel family. Inclusion of Mo or W to form ternary alloys improves the thermal stability of electroless nickel coatings. Therefore, in the present work, Ni-B, Ni-B-Mo, and Ni-B-W coatings are deposited; and their tribological behavior at room and high temperatures are investigated. Electroless Ni-B, Ni-B-Mo, and Ni-B-W coatings are deposited on AISI 1040 steel substrates. The coatings are heat treated to improve their mechanical properties and crystallinity. Tribological behavior of the coatings is determined on a pin-on-disc type tribological test setup using various applied normal loads (10-50 N) and sliding speeds (0.25-0.42 m/s) to measure wear and coefficient of friction at different operating temperatures (25 • C-500 • C). Ni-B-W coatings are observed to have higher wear resistance than Ni-B or Ni-B-Mo coatings throughout the temperature range considered. Although for coefficient of friction, no such trend is observed. The worn surface of the coatings at 500 • C is characterized by lubricious oxide glazes, which lead to enhanced tribological behavior compared with that at 100 • C. A study of the coating characteristics such as composition, phase transformations, surface morphology, and microhardness is also carried out prior to tribological tests. Lubricants 2018, 6, 67 2 of 17The Ni-B alloy coating has higher wear resistance and low COF compared with Ni-P alloy [23]. This is attributed to the high hardness, self-lubricating microstructure and columnar growths [24]. Consequently, a reduction in the actual contact area takes place, thereby improving the tribological characteristics [25]. Suitable treatments of Ni-B coatings may even lead to microhardness that is equivalent to chromium [26]. As a result of this, Ni-B coatings are considered to be a suitable alternative to chromium, which has environmental concerns. Friction and wear characteristics of magnesium and aluminium alloys that are widely used commercially could be improved by Ni-B alloy deposition [27]. An improvement of tribological behavior of Ni-B coatings is also achieved on inclusion of W or Mo [28,29]. In fact, co-deposition of nano Al 2 O 3 results in an increase in microhardness bỹ 290 HV 100 [30]. The mass loss and COF of Ni-B-Al 2 O 3 coatings is almost six and two times lower, respectively, in comparison with Ni-B alloy in as-deposited state. Similar results have been also observed on inclusion of B 4 C nano-particles [31]. Impregnation of Ni-B coatings with PTFE (40%) results in a COF as low as <0.1 in non-lubricated, as well as 3.5% NaCl lubricated sliding condition [32]. Electroless Ni-B coatings have been applied in greaseless guns and barrel bores that are subjected to hostile environments proving to be a suitable replacement to chromium [33]. Recent studies have focused attention on duplex and multi-layer coatings that possess intermediate/enhanced tribological characteristics compared with the single layered binary alloys [34,35]....

Some researchers have developed oxide dispersion strengthened MCrAlX coatings, suggesting the hard phases strengthen the alloy matrix by impeding the motion of dislocations [33][34][35][36]. Additionally, after oxidation test at 200°C and 400°C, the microhardness of the CoCrAlYTa-10%Al 2 O 3 coating and H13 steel was basically the same as that at room temperature.…”

The CoCrAlYTa-10%Al 2 O 3 coating was fabricated on H13 steel substrate using high-velocity oxygen fuel (HVOF) thermal spraying. A detail characterization on the microstructures, element distribution and phase composition of the HVOF sprayed CoCrAlYTa-10%Al 2 O 3 coating was conducted using scanning electron microscopy (SEM) equipped with energy-dispersive spectroscopy (EDS), x-ray diffraction (XRD) and transmission electron microscopy (TEM). The microstructural evolution and microhardness of the coating at different temperatures were investigated. The results showed that the coating had a dense and uniform microstructure with a low porosity of 0.44%. The primary phases for the CoCrAlYTa-10%Al 2 O 3 coating were identified as Co-based solid solution, Cr-based solid solution, Al 2 O 3 phase and TaC particles. Compounds such as Cr 7 C 3 , Al 13 Co 4 and aluminum-yttrium oxides Al 5 Y 3 O 12 were also confirmed by TEM observation results. Owing to the rapidly cooling rates of the molten droplets, nano-crystalline phase was existed in the coating. The average microhardness of the coating was 640 HV 0.1 . Its high microhardness derived from the presence of certain volume fraction of hard Al 2 O 3 , Cr 7 C 3 and TaC grains within the coating. After 1h of oxidation, oxides like CrO 2 and Ta 2 O 5 were formed when the coating exposed at the temperature up to 800°C. At the temperature above 600°C, the hardness of the coating remained at a high level (600 HV 0.1 ). It possessed better high temperature softening resistance than H13 steel, indicated that the coating exhibited good mechanical properties at high temperature.
