Dimensional distortion occurs due to the thermal and transformation stresses formed during the heat treatment processes. Taguchi and Factorial design of experiment concepts were applied to optimize the operating variables involved in the gas carburising and induction hardening processes so as to minimize the geometrical distortions. Experimental data obtained for the materials EN353, EN351, AIS...

Previous studies have established that some of the wear damage seen on cast CoCrMo joint surface is caused by entrained third-body hard particles. In this study, wet-cell micro-indentation and nano-scratch tests have been carried out with the direct aim of simulating wear damage induced by single abrasive particles entrained between the surfaces of cast CoCrMo hip implants. In situ electrochemi...

in recent years noise has been well known as an environmental pollution. particularly its effects will be more serious in some environments including hospitals which patients need a calm and peaceful condition. this study aims to evaluate hospitals noise pollution level. this study is a cross-sectional study. noise measurements were made in all hospital wards in a workday and weekend from 8 to ...

In this work, the inhibition effect of a non-ionic gemini surfactant, named bis(2-((2-palmitoamidoethyl)amino)ethyl)1H-imidazole4,5-dicarboxylate, on stress corrosion cracking (SCC) behavior supermartensitic stainless steel (SMSS) was studied in sour environment. The slow strain rate tests (SSRT) results and fractographic analysis revealed that inhibitor able to inhibit SCC process using concen...

Fast scan cyclic voltammetry (FSCV) is an electrochemical method commonly used in neuroscience for spatiotemporal measurement of the concentration of dopamine and other electroactive species. Since FSCV involves wide bandwidth measurements of low currents, the technique is normally very sensitive to electrical noise and is typically performed inside a Faraday cage. In order to reduce the electr...
