1) non metallic oxide inclusion 非金属氧化物夹杂 1. By hardness test and microstructure analysis, the workability of prehardened die steels 3Cr2MnNiMo and ASSAB718 for large die for plastics were compared The results show that the new 3Cr2MnNiMo steel has better workability However the inhomogeneous...
Through the mixing ratio of the multi-color film of the metal material and nitrogen oxide hydrocarbon gas was adjusted so that the non-metallic substrate can show iridescent metallic color and showed more different gradient.张义忠杨明晃蔡建松黄丽花...

(Cu2O; standard enthalpy of formation ΔH°f = −170 kJ mol–1) and cupric oxide (CuO, ΔH°f = −156 kJ mol–1), respectively, in air1. This inevitable formation of Cu oxides under ambient conditions deteriorates the metallic properties of Cu, and the process ...
Precipitates in an austenitic stainless steel fabricated via any Additive Manufacturing (AM), or 3D printing, technique have been widely reported to be only Mn-Si-rich oxides. However, via Transmission Electron Microscopy (TEM) studies on a 316L stainless steel, we show that non-oxide precipitates...
aAn inter-metallic bond must be formed at the interface of solder and the base metal surfaces. The bonding of non metallic substrates like glasses is based on the chemical reaction of CERASOLZER by creating a specific oxide layer 必须形成金属间化合的债券在焊剂和碱金属表面接口。 非金属基体接合...

The paper presents an isotopic method for the determination of oxide inclusions in steel, formed during the process of steel deoxidation with aluminium and silicon. In view of the lack of adequate radioactive isotopes of both mentioned elements, the developed method consists in the use of ...
As monometallic catalysts, Cu and Ti are known to be poor HER catalysts because their HBE values are either too small or too large, respectively36. Using DFT calculations, we have demonstrated that the Cu-Cu-Ti hollow site on a Cu-Ti bimetallic surface exhibits an optimal HBE for HER. As...
A thorough comprehension of the mechanism behind organic electrooxidation is crucial for the development of efficient energy conversion technology. Here, we find that trivalent nickel is capable of oxidizing organics through a nucleophilic attack and electron transfer via a nonredox process. This nonredox...
