“…Furthermore, the lower plasma bombardment (200 mW·cm −2 ) readily produced the loose sp 2 bond, while the higher plasma bombardment (800 mW·cm −2 ) led to greater internal stress and more uneven sp 3 and sp 2 structures. The VDI 3198 indentation test 17) showed the adhesion strength of the power densities of 400 and 600 mW·cm −2 DLC lm treatments to be the HF 1 grade and the 200 and 800 mW·cm −2 the HF 1 2 grade. Figure 5 shows the surface morphology observations of the scratch tests after the different power densities of the DCpulsed PECVD process.…”

In this work, DLC lms are prepared by DC-pulsed PECVD after the oxynitriding treatment of V4E high vanadium tool steel. The experimental design includes various power densities (200, 400, 600 and 800 mW·cm ) with an unbalanced bipolar-pulsed voltage. The deposition time is 90 min, and the CH 4 gas ow is maintained at 5 sccm, respectively. The experimental results show the duplex coating layers to have better properties when the DLC lms are treated by an appropriate power density (400 mW·cm ) and the highest polarization resistance (258.83 Ω·cm 2 ) after the 3.5 mass% NaCl corrosion test. This study con rms that the wear and corrosion resistance of V4E tool steel can be effectively improved through the DLC/oxynitriding duplex treatment.

“…In order to evaluate the wear and corrosion behaviors of DLC/oxynitriding treated PM60 high-speed steel, the Raman spectroscopy analysis (Horiba MOF-iHR550), wear test (POD-FM406), indentation test (Indentec-8150LK), 15) XRD (Rigaku DMX-2000) and SEM (Hitachi-S4700) microstructure observations were performed. The wear resistance of the specimens was evaluated in a ball-on-disk test (ASTM G99).…”

“…A careful observation of the SEM images made it reasonable to judge that the adhesion strength of the DLC films for the 200 mW·cm − 2 specimen belonged to the HF 1-2 grade. 15) In fact, the radial cracks, which are caused by the compressive stress on the specimen's surface during the oxynitriding process, did not generate fractures in the DLC films.…”

In this study, diamond-like carbon (DLC) films are prepared by DC-pulsed plasma-enhanced chemical vapor deposition (PECVD) after the oxynitriding treatment of PM60 high-speed steel. The chief study of the parameters of a DC-pulsed PECVD process includes various power densities (200, 400, 600, 800 and 1 000 mW·cm − 2 ) with unipolar negative-pulsed voltage. In order to evaluate the properties of the DLC films for DLC/oxynitriding-treated PM60 high-speed steel, Raman spectroscopy analysis, wear tests, hardness tests, Rockwell indentation and corrosion resistance inspections are performed. The experimental results show the duplex coating layers to have the ideal properties when the DLC films are treated by the unipolar negative-pulsed voltage, a deposition time of 90 min and duty cycles maintained at 11%, with an appropriate power density (400 mW·cm − 2 ), respectively. The DLC/oxynitriding duplex treatment results in the highest surface hardness (Hv 0.2 2 516.4) and lowest wear volume loss (when the load of 2 N and 5 N is 2.36 × 10 − 3 mm 3 and 5.67 × 10 − 3 mm 3 , respectively). In addition, when the DLC/oxynitriding duplex film is treated by a power density of 200 mW·cm − 2 , it possesses the lowest corrosion current (I corr = 7.24 × 10 − 5 A·cm − 2 ) and highest polarization resistance (R p = 6.26 × 10 2 Ω·cm 2 ) in 3.5 wt% NaCl solutions. The test results confirm that the optimal wear and corrosion resistance can be acquired by the DLC/ oxynitriding duplex treatments.

“…This well-known Rockwell-C indentation test is prescribed by the VDI 3198 norm, as a destructive quality test for coated compounds. [17][18][19][20] The principle of this method is presented in the upper-right-hand part of Figure 1. 18 A load of 1471 N was applied to cause coating damage adjacent to the boundary of the indentation.…”

In the present study the effect of the boriding process on the adhesion and wear properties of AISI H10 steel has been investigated. The boride layer was characterized by light microscopy, X-ray diffraction and the Vickers microhardness. The X-ray diffraction analyses of the boride layers on the surface of the steels revealed the existence of the compounds FeB, Fe2B, CrB, Cr2B and MoB. Depending on the chemical composition of the steel, the boride-layer thickness on the surface of the AISI H10 steel was found to be 63.72 μm. The hardness of the boride compounds formed on the surface of the steels ranged from 1648 to 1964 HV0.05, whereas the Vickers hardness value of the untreated steel was 306 HV0.05. The wear tests were carried out in a ball-on-disc arrangement under dry-friction conditions at room temperature with an applied load of 10 N and with a sliding speed of 0.3 m s -1 for a sliding distance of 1000 m. It was observed that the wear rate of the borided and non-borided AISI H10 steels ranged from 3.15 mm 3 /N m to 62.84 mm 3 /N m.Keywords: AISI H10, boriding, microhardness, adhesion, wear rate V predstavljeni {tudiji je bil preiskovan vpliv postopka boriranja na adhezijo in obrabne lastnosti jekla AISI H10. Borirana plast je bila karakterizirana s svetlobno mikroskopijo, z rentgensko difrakcijo in z merjenjem mikrotrdote po Vickersu. Analiza z rentgensko difrakcijo borirane plasti na povr{ini jekel je odkrila prisotnost spojin: FeB, Fe2B, CrB, Cr2B in MoB. Odvisno od kemijske sestave jekla je bila debelina borirane plasti na povr{ini jekla AISI H10 okrog 63,72 μm. Trdota borovih spojin, ki so nastale na povr{ini jekel, je bila med 1648 HV0,05 do 1964 HV0,05, medtem ko je bila Vickers trdota neobdelanega jekla 306 HV0,05. Izvr{eni so bili preizkusi obrabe z napravo s kroglico na plo{~i pri pogojih suhega trenja pri sobni temperaturi z uporabljeno obremenitvijo 10 N, s hitrostjo drsenja 0,3 m/s pri dol`ini drsenja 1000 m. Hitrost obrabe boriranega in neboriranega jekla AISI H10 je bila v obmo~ju od 3,15 mm 3 /N m do 62,84 mm 3 /N m.
