WhatsApp: +86 18203695377Conclusions. Longtime (3000h) hightemperature (800 °C) steam oxidation testing simulating the service conditions in the Advanced UltraSupercritical coalfired power plants was conducted to investigate and compare the behaviour of the aluminized thermal diffusion coatings deposited on 310S and 800H substrates vs. bare materials.
WhatsApp: +86 18203695377Microhardness of the studied bare materials became lower after oxidation testing; it can be especially noted for the surface of the samples. Thus, microhardness became ~200230 and 170200 kgf/mm 2 for 310SS and 800H, respectively (see Table 4). Again, it may be related to the grain growth during hightemperature longtime exposure ...
WhatsApp: +86 18203695377The compaction properties of powders can be assessed using target force or target distance modes. Many powder compacts are formed to a target distance and so this test can be used to assess the force required to reach this distance. However, new advances in tableting machines allow compression to a target force (resulting in powder compacts ...
