Nickel-based and cobalt-based metal alloys are frequently used in dentistry. The introduction of various elements the alloy changes its characteristics, a thorough study each should be completed to determine appropriate corrosion resistance biocompatibility contact with physiological fluids. There scarce investigations on these widely dental Ringer solution, findings this research bring new exp...

In this study, a Cr3C2-NiCr cermet cladding layer was prepared on the surface of Q235 steel via high-speed laser method. The effects power, scanning speed, and overlap rate microstructure, quality, interfacial elements diffusion Cr3C2-NiCr/Q235 were studied. results show that there an obvious transition at interface steel, indicating had adequate metallurgical bond with matrix. Fe, Cr, Ni diffu...

PURPOSE OF THE RESEARCH To investigate the prevalence and nature of unmet needs among colorectal cancer (CRC) survivors and the relationship between needs and quality of life (QoL). METHODS AND SAMPLE Using the Northern Ireland Cancer Registry (NICR) as a sampling frame and working in collaboration with primary care physicians or GPs, the Cancer Survivors Unmet Needs (CaSUN) questionnaire and...

A comparative study of the corrosion resistance of CoCr and NiCr alloys in artificial saliva (AS) containing tryptic soy broth (Solution 1) and Streptococcus mutans (S. mutans) species (Solution 2) was performed by electrochemical methods, including open circuit potential measurements, impedance spectroscopy, and potentiodynamic polarization. The adherence of S. mutans to the NiCr and CoCr allo...

The felling of a telecommunications mast highlighted a community's concern regarding an alleged cancer cluster of eleven cases in a small rural area of Northern Ireland. At the request of the Local District Council, the Northern Ireland Cancer Registry (NICR) undertook an investigation. After extensive searching and contact with the community, only 6 of the alleged cases could be identified. Of...

A top DLC film was deposited on the surface of Cr3C2-NiCr coated 38CrMoAl steel substrate, and effect cermet interlayer thickness mechanical tribological properties duplex coating investigated by experimental analysis finite element modeling (FEM). Results shown that, compared with single film, load-bearing capacity performance DLC/Cr3C2-NiCr were significantly improved, especially its anti-wea...
