"tin Coatings for Wear Resistance and Gold-like Decorative Coatings"
Titanium Nitride (TiN) coatings have led the way for providing increased wear resistance and extended life of cutting tools, whether carbide inserts or high-speed steel. Where the earliest applications were for high temperature substrate materials (carbides) and chemical vapor deposition (CVD) was the process of choice, later developments in the physical vapor deposition (PVD) technology, espec...
متن کاملNanohardness and Residual Stress in TiN Coatings
TiN films were prepared by the Cathodic arc evaporation deposition method under different negative substrate bias. AFM image analyses show that the growth mode of biased coatings changes from 3D island to lateral when the negative bias potential is increased. Nanohardness of the thin films was measured by nanoindentation, and residual stress was determined using Grazing incidence X ray diffract...
متن کاملextraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties
آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
15 صفحه اولEffect of Gas Ratio on Tribological and Corrosion Properties of Ion Beam Sputter Deposited TiN Coatings
Titanium nitride thin films were grown on 304 stainless steel substrates at various nitrogen/argon flow ratios by ion beam sputtering (IBS) technique. The current research is a follow up study on the influence of gas ratio on structural and corrosion properties in the TiN coated 304 stainless steel. Film structural identification of phases was performed using X-ray diffractometry (XRD). Sca...
متن کاملCOMPARISON OF THE CrN , TiN AND (Ti, Cr)N PVD COATINGS DEPOSITED BY CATHODIC ARC EVAPORATION
In the present study, CrN, TiN and (Ti, Cr)N coatings were deposited on D6 tool steel substrates. Physical and mechanical properties of coatings such as microstructure, thickness, phase composition, and hardness were evaluated. Phase compositions were studies by X-ray diffraction method. Mechanical properties were determined by nano-indentation technique. The friction and wear behaviour of the ...
