The Effect of Dopants on Structure Formation and Properties of Cast SHS Alloys Based on Nickel Monoaluminide.

Alloys based on NiAl-Cr-Co () with complex dopants () were fabricated by centrifugal SHS metallurgy. The phase and impurity compositions, structure, mechanical properties, and the mechanism of high-temperature oxidation at T = 1150 °C were studied; the kinetic oxidation curves, fitting equations and parabolic rate constant were plotted. AlO and CoCrO were the major phases of the oxidized layer.

The Effect of Copper on the Microstructure, Wear and Corrosion Resistance of CoCrCuFeNi High-Entropy Alloys Manufactured by Powder Metallurgy.

This paper focuses on the microstructure, phase composition, mechanical, tribological and corrosion properties of high-entropy alloys (HEAs) in the CoCrCuFeNi system depending on copper content, which was varied from 0 to 20 at. % with an increment of 5%. CoCrCuFeNi alloys were manufactured by powder metallurgy methods: mechanical alloying and hot pressing of element mixtures.

Prevalence and Risk of Dental Erosion in Patients with Gastroesophageal Reflux Disease: A Meta-Analysis.

Aim: The present paper aims to systematize data concerning the prevalence and risk of dental erosion (DE) in adult patients with gastroesophageal reflux disease (GERD) compared to controls.

Materials And Methods: Core electronic databases, i.e.

[Comparative evaluation of the shear bond strength of a universal adhesive system in different etching modes and a total etch adhesive system].

Objective: To determine a comparative evaluation between the shear bond strength (SBS) of total etch adhesive system and the SBS of universal adhesive system in various etching techniques.

Material And Methods: There were made 60 sections of teeth for the laboratory research. The studied samples had been divided into 4 groups (15 samples in each group).
