Microstructure and Wear Resistance of Ti5Si3/Ti3Al Composite Coatings Prepared by Laser Cladding on TA2 Titanium Alloy

open access: yesLubricants, 2023
In order to improve the wear resistance of titanium alloy, a Ti5Si3/Ti3Al composite coating with improved wear resistance was successfully prepared by laser cladding TA2 titanium alloy using the double-layer presetting method of Ti-63 wt.% Al mixed ...

Structural evolution of Ti–Al–Si–N nanocomposite coatings [PDF]

open access: yesVacuum, 2009
Abstract Ti–Si–Al–N films were prepared by rf reactive magnetron sputtering, in static and rotation modes, using a wide range of different deposition conditions, which created conditions to obtain Ti–Al–Si–N coatings with different structural arrangements.

Thermal cyclic resistance and long term inter-diffusion properties of slurry aluminide coatings modified with Si

open access: yesResults in Surfaces and Interfaces, 2022
High temperature oxidation resistant aluminide coatings fail due to their inability to maintain a protective scale. The corresponding mechanism of protection is based on of forming a thin Al2O3 layer, which depends on the availability of Al at the ...

Nano-scale analysis of titanium dioxide fingerprint-development powders [PDF]

open access: yes, 2008
Titanium dioxide based powders are regularly used in the development of latent fingerprints on dark surfaces. For analysis of prints on adhesive tapes, the titanium dioxide is suspended in a surfactant and used in the form of a small particle reagent ...

Phase assemblage and wear resistance of laser-cladding Al0.8FeCoNiCrCu0.5Six high-entropy alloys on aluminum

open access: yesMaterials Research Express, 2020
Preparing a coating with excellent mechanical properties on aluminum substrates by laser cladding has always been challenging because of the low melting point and high chemical activity of Al. In this study, we designed Al _0.8 FeCoNiCrCu _0.5 Si _x (x =

Effect of ion irradiation on tribological properties of composite coatings [PDF]

open access: yes, 2015
The paper discusses the results of the research in the effect of ion irradiation on tribological properties of multiphase ion-plasma coatings. It is shown that all the investigated coatings behave differently under ion irradiation: the Zn-Al, Fe-Al, Zn ...

Structure of Ti-Al-Si-N gradient coatings

open access: yesTechnical Physics, 2015
The microstructure, the stresses, and the elemental composition of Ti-Al-Si-N gradient coatings are studied by transmission electron microscopy and electron-probe microanalysis of thin foils prepared in the cross section of the coatings. As the concentration of the elements that alloy titanium nitride increases across the coating thickness, the ...

Investigation on Mechanical Properties and Oxidation Behavior of 1.2 and 1.7 GPa Grades Coating-Free Press-Hardened Steels

open access: yesMetals, 2023
Al-Si-coated boron-alloyed steels are the most widely used press-hardened steels (PHSs), which offers good oxidation resistance during hot forming due to the presence of the near eutectic Al-Si coating. In this study, a recently developed novel un-coated
