In the present work, a low-pressure chemical vapor deposition (LPCVD) Ti0.17Al0.83N and state-of-the-art arc ion plating PVD-Ti1−xAlxN (x = 0.25, 0.55, 0.60, 0.67) coatings were deposited on cemented carbide substrate. The morphological, structural, electrochemical properties of LPCVD-Ti0.17Al0.83N compared. X-ray diffraction (XRD) results scanning electron microscopy (SEM) images revealed that...

Chromium oxide coatings are chemically inert, have high mechanical strength, hardness and good optical characteristics; therefore, they have been widely used in many applications including corrosion protection, wear resistance, electronics, and optics. Cr2O3 is well suited for wear resistance applications, as it is one of the hardest oxides with 29.5 GPa hardness. Several deposition techniques ...

The design of multilayer stack of dielectric films for narrow band mirror is developed using thin film coating software. The proposed design is materialized by employing thin film coating (PVD) method and reflectance in narrow band spectrum range is achieved. Thickness of high and low refractive index material is taken precisely up to nanometer level. The curved coated substrate is cemented wit...

The spindle is the key working part of horizontal cotton picker, and wear resistance its surface directly affects service life spindle. Improving performance fundamental for improving pickers. To enhance surface, this study used physical vapor deposition (PVD) technique to prepare TiN coating on substrate cotton-picking machine improve rather than original electroplated chromium coating. micros...

In this review, several cost-effective thin-film coating methods, which include dip-coating, spin-coating, spray-coating, blade-coating, and roll-coating, are presented. Each method has its own set of advantages disadvantages depending on the proposed application. Not all them appropriate for large-scale production due to their certain limitations. That is why should be selected based type size...

In this research work, an experimental evaluation was conducted to explore the fretting fatigue life of multilayer Cr–CrN-coated AL7075-T6 alloy specimens with higher adhesion strength to substrate as the coating adhesion strength is one of the most critical issues in magnetron sputtering technique. Physical vapor deposition (PVD) magnetron sputtering technique was used for coating purpose, and...

The 316 L Stainless Steel is widely used as structural material in marine applications and subject to localized pitting corrosion chlorinated environments. main aim of the present work development coatings that are alternately deposited by a combination Physical Vapor Deposition (PVD) Atomic Layer (ALD) techniques. Three different architectures PVD/ALD, ALD/PVD PVD/ALD/PVD were studied. layer A...

In the aluminum die casting process, erosion, corrosion, soldering, and die sticking have a significant influence on tool life and product quality. A number of coatings such as TiN, CrN, and (Cr,Al)N deposited by physical vapor deposition (PVD) have been employed to act as protective coatings due to their high hardness and chemical stability. In this study, the wear performance of two nanocompo...

Thermal barrier coatings (TBCs), consisting of physical vapor deposited (PVD) partially stabilized zir-conia (PSZ, 8 wt. %Y203) and a diffusion aluminide bond coat, were characterized as a function of time after oxidative isothermal heat treatment at 1373 K in air. The experimental characterizations was conducted by X-ray diffraction analysis and scanning electron microscopy (SEM) with energy-d...
