“…Except the pattern of substrate, it can be seen that the CrAlSiN layer is comprised of (111), and (200) crystalline planes. The result means FCC structure of the CrAlN embedded in the SiNx matrix [1][2][3][4]. As for the other two DLC layers, the XRD results show no obvious diffraction peak except the substrate.…”

“…Shot blasting treatment can improve the steam oxidation resistance of austenitic steel compared with previous report [17]. Abusuilik has investigated the effects of various surface treatments on the properties and performance of the hard coating, and found that material transfer and build-up at the coating surface were higher for the surfaces treated by grinding and shot blasting than those treated by other methods [18]. During the open pore metallic foam core sandwich panels prepared by thermal spraying of a coating, Salavati found that the coating porosity and adhesion strength were determined by the substrate surface roughness, which could be controlled by grit-blasting parameters [14].…”

Grit blasting is one simple but effective method to modify the morphology of material surface and can improve the tribological performance. In this study, a thick TiN film was prepared by arc ion plating on the steel disk treated with grit blasting, and the rough surface coated solid film was obtained. The tribological properties of solid film against different materials were evaluated under starved lubrication regime. The results showed that the friction coefficients of rough titanium nitride (TiN) films were lower than those of rough steel disks exclude alumina ball under starved lubrication, and the wear rates of TiN film were negligible due to the high hardness of TiN film and small contact area. For four kinds of balls including steel ball, silicon nitride, zirconia, and alumina, the wear scar diameter of steel ball is biggest, and the wear scar diameters of other balls are small. The hardness of steel ball is less than others, which results in the easy abrasion and increases the contact area to reduce the pressure. So the friction coefficient of TiN against steel is low and steady.

Abstract. Turning tools come in different shapes and sizes, geometry, base material and coating, according to their destination. They are widely used both for obtaining parts and for machinability tests. In this paper a short review about high-speed steel (HSS) turning tools and their coatings is presented. Hard coatings formed on the tool material should be functional depending on the tool final application. Requirements for hard coatings and technological problems for layer formation on the real cutting tool are discussed. Techniques and production of hard coatingsIn a statistical study made for the year 2013 [1] the 16.33 billion US-Dollars estimated industry of cutting tools includes 39% milling tools followed by 30% of turning tools, with an annual growth assumed to be 4-5%. The same study shows that in 53% of the cases, the cutting tool substrate is represented by cemented carbide and in 20% of the cases by highspeed steel (HSS).Coatings on cutting tools are widely spread due to the improvement they provide during the cutting process. In the early 2000's made statistic 50% of HSS tools, 85% of carbide tools and 40% of super-hard tools used in industry were coated [2]. Due to the more complex phenomenology which accompanies the intermittent cutting process, in this study only coatings of HSS turning tools will be treated.The use of coatings is expected to yield a better protection of the tool against abrasion and adhesion, diffusion, oxidation and to produce a heat barrier for the intensive heat flowing from the cutting area into the tool material [3], thus increasing productivity and tool's life. However, regarding the heat insulation the opinions are divided, as in the paper [4] it was proven that the coatings of continuous cutting tools are not able to insulate the substrate.Mainly, depending on the method and the coating structure, the same coatings can be applied to both HSS and carbide tools, each substrate having its advantages and disadvantages according to the cutting application. The properties of the tools surface should be improved according their novelty, application and to achieve higher productivity for the manufacturing process. Depending on the turning tools destination various hard coatings can be formed on its surface. The shape of the turning tool is usually not complicated, thus techniques like physical or chemical vapor deposition for layer formation are applied. Hard *
