High oxidation resistance mechanism

In summary, vitamin-E-diffused, irradiated UHMWPE showed high oxidation resistance in vitro under accelerated aging and under real-time aging up to 36 months. Aggressive oxidation caused by accelerated aging combined with deformation was also hindered in this material at 5 weeks. Based on this information, it is likely that this material will retain its mechanical properties in vivo as well. 

Magnetic nanoparticles (NPs), in particular iron oxide magnetic nanoparticles exhibit remarkable magnetic properties particularly in radiofrequency region, physical flexibility, high electrical resistivity, mechanical hardness and chemical stability. They have found widespread applications in many fields covering... 

Since the paper by Pilling and Bedworth in 1923 much has been written about the mechanism and laws of growth of oxides on metals. These studies have greatly assisted the understanding of high-temperature oxidation, and the mathematical rate laws deduced in some cases make possible useful quantitative predictions. With alloy steels the oxide scales have a complex structure chromium steels owe much of their oxidation resistance to the presence of chromium oxide in the inner scale layer. Other elements can act in the same way, but it is their chromium content which in the main establishes the oxidation resistance of most heat-resisting steels. 

NixAlj x (homogeneous between 42 and 69 at.% Ni) with good mechanical and oxidation resistance properties. By quenching from high temperatures the formation of an ordered martensite is obtained which can be considered for its shape memory behaviour. For a discussion on substitutional additions to CsCl-type alloys (site preference for dilute additions to NiAl, FeAl, CoAl, etc.) see Kao et al. (1994).
