“…7c) exhibited less severe adhesive and abrasive wear than in the other lubri-cooling states. As mentioned earlier, NMQL provides a low cooling rate; at the same time, its lubricating effect is evident, reducing the friction in the tool-chip and tool-workpiece interfaces without resulting in intense material work hardening [19].…”

The application of super austenitic stainless steels (SASS) in the petroleum, chemical, and naval industries has gradually increased owing to their intrinsic properties, such as corrosion resistance and durability. Consequently, the low machinability of SASS is due to its high mechanical strength, low thermal conductivity, and high tendency to work hardening. The present work analyzes the influence of different cutting and lubri-cooling conditions on machining forces, tool wear, surface roughness, and chip features produced during end milling of SASS 254 SMO.The results showed that depth of cut was the most influential parameter on static and dynamic machining forces, whereas the effect of cutting speed was low expressive. The nanofluid minimum quantity lubrication provided more stability in force values and lower tool failures on the peripheral cutting edge for the total machined length than in flood condition. In comparison, dry machining resulted in higher tool failure and machining forces. Low roughness values were generated on the sample surface because the end-cutting edge did not exhibit substantial failures. The lubricating effect of NMQL also improves the surface quality of the machined workpiece. On the other hand, dry machining resulted in adhered materials owing to high temperatures in the cutting zone and flood milling in removing material particles from the surface due to work hardening. Furthermore, the generated chips corroborated the analysis of the lubri-cooling effects on the machinability of the material, highlighting the higher temperatures produced during dry cutting owing to changes in the surface color of chips.

“…Although austenitic stainless steels (ASS) are broadly used in industries because they have excellent corrosion resistance, their low yield strength restricts applications in harsh environments and may necessitate searching for a suitable substitute (Avilaa et al, 2020), (Alabdullah, Polishetty and Littlefair, 2016), (Moharana et al, 2016). Super austenitic stainless steels (SASS) have superior mechanical properties and corrosion resistance (Polishetty, Alabdullah and Littlefair, 2017), (Qiao et al, 2019). Therefore, SASS has been used in important applications like petrochemical equipment, saltwater pumps, and deep-water oil exploration fittings (Sathiya, Mishra and Shanmugarajan, 2012), (Alabdullah et al, 2017).…”

Due to the relatively high wear rate of the austenitic stainless steel S30400 and the high mechanical properties of the super austenitic stainless steel S31254, it was possible to compare the wear behavior of the two alloys and select the best alloy to extend the service life of sliding parts. In this work, wear tests were performed at five different temperatures (30°C, 140°, 300°C, 460°C, and 570°C) at constant sliding speed, applied load, and sliding distance for both alloys. The specific wear rate of S31254 was more than 50% lower compared to S30400 at the different temperatures, except at 570°C, where it was only 16%. According to scanning electron microscopy and X-ray diffraction, oxide formation on the worn surfaces started at 300°C and increased with increasing temperature. The oxide layers protected the surface and reduced wear and material removal. Overall, S31254 exhibited better wear resistance at various temperatures.

“…Another trend in cutting tools is their preservation with single-layer coatings of polycrystalline diamond (PCD) or common boron nitride (CBN). The protective coatings can be deposited to the working surfaces of cutting tools with two methods: CVD (Chemical Vapour Deposition) or PVD (Physical Vapour Deposition) [16][17].…”

The paper presents an assessment of the wear rate of turning tool blades during machining of steels applied in medical industry. The subjects of the research were stainless steels X20Cr13 (1.4021) and X8CrNiS18-9 (1.4305) used in production of surgical instruments. An experiment was carried out to assess the wear of multi-edge turning inserts with CVD coatings (Pafana CNMG 12 04 08 ZSZ and Sandvik CNMA 12 04 12-KR 3205), and an uncoated turning insert (Sandvik CNGA 12 04 08 T0102 WG 650). The wear was measured by the direct wear indicator VB C. On the basis of the results obtained for both X20Cr13 and X8CrNiS18-9, it was found that the Pafana CNMG 12 04 08 ZSZ turning insert had the best wear resistance during machining. The cutting path of Pafana CNMG 12 04 08 ZSZ was about 25 % longer than Sandvik CNMA 12 04 12-KR 3205 and about 300 % longer than Sandvik CNGA 12 04 08 T0102 WG 650. It was also found that each turning insert revealed a linear wear.
