Anodizing is expected to be an effective method to improve the osteoconductivity of the Ti-29Nb-13Ta-4.6Zr (TNTZ) alloy because the bioactivity of anodized Ti is good. However, it is not known how the alloy elements influence the surface roughness, composition, hydrophilicity, and osteoconductivity of the anodized film on the Ti alloy. In this study, we investigated the effects of anodizing on ...

The oxidation and porcelain fusion characteristics of noble alloys containing a variety of minor oxidizable elements, including Cu, Sn, In, Ga, Mn, and Fe were investigated. Four porcelain alloys systems: a Pd-base alloy (Naturelle}, two Pd-Ag-based alloys (Jelstar and Acclaim}, and a high Au-alloy (SMG-3) were examined by scanning electron microscopy and energy dispersive spectroscopy after be...

The effect of lanthanum implantation on the early stage oxidation of Fe-18wt%Cr5wt%Al and Fe-l8wt%Cr-5wt%Al-Iwt%Hf alloys at 1100 OC has been investigated. I t was found that the reactive element enriched surfaces oxidized almost two times faster initially, and the scale that formed had a higher iron content. An extremely wavy scale/alloy interface developed in the early stage due to the accele...

background: dental cobalt base alloys are biocompatible dental materials and have been widely used in dentistry. however, metals are bioinert and may not present bioactivity in human body. bioactivity is the especial ability to interact with human body and make a bonding to soft and hard tissues. the aim of the present research was fabrication and bioactivity evaluation of novel cobalt alloy/ f...

Babbitt is a white silvery alloy that composed of Tin, Lead, Copper and Antimony. This alloy is the most current bearing alloy in industrial applications. The characteristics of this alloy, such as high wearing resistance and low coefficient of friction, have converted it into a bearing cover. The target of this study is investigation on the effects of alloy elements on wearing and micro-struct...

Titanium alloy and stainless steel (SS) had been widely used as dental implant materials because of their affinity with epithelial tissue and connective tissue, and good physical, chemical, biological, mechanical properties and processability. We compared the effects of titanium alloy and SS on macrophage cytokine expression as well as their biocompatibility. Mouse macrophage RAW264.7 cells wer...

Ultrathin 2D metal alloy nanomaterials have great potential applications but their controlled syntheses are limited to few noble metal based systems. Herein Ni x Co1-x alloy nanosheets with ultrathin (sub-3 nm) single-crystalline 2D structure are synthesized through a topochemical reduction method. Moreover, the optimized composition Ni0.6Co0.4 alloy nanosheets array exhibits excellent performa...

the microleakage of cinaally amalgam, manufactured by dr faghihi co. which is a high copper alloy and fine-cut amalgam was evaluated by radioisotope agents. the microleakage of cinaally amalgam was compared with sybraloy amalgam, manufactured by sybron/kerr co. which is a high copper alloy and spherical shape amalgam and is known as a standard amalgam alloy. the results showed that there is no ...

An example of an object model is given in full in three languages: Alloy, a new notation; Z, a formal specification language; and UML, a modelling notation popular in industry. Basic features of Alloy are explained informally, and briefly justified by comparison of the Alloy version to the UML and Z versions.
