Abstract As the environment deteriorates, recycling of solid waste has become increasingly important. This study aimed to optimize use Fe 2 O 3 , SiO and CaO components in coal fly ash convert into stable porous Al TiO 5 ‐mullite ( AT –M) composite ceramic by sintering with OOH additives at high temperatures. The phase composition, microstructure, apparent porosity, corrosion resistance, mechanical properties –M ceramics were systematically investigated. Results indicated that sintered...
The plasma sprayed Fe-based Ni/WC composite coating on the surface of 45 steel was post-treated by laser remelting with addition nano-SiC. effect power interface microstructure a nano-SiC modified coatings were researched. metallographic structure, microscopic morphology, phase composition, and microhardness remelted layer visually analyzed microscope, scanning electron microscope (SEM), X-ray diffractometer (XRD), tester, respectively. results showed that smooth compact, no fine cracks....
The high-energy laser melts the cladding materials which coagulate onto surface of base materials. coatings are produced mainly in two methods: powder feeding and prefabricating. grain-strengthening composite could be formed more easily by prefabricating method than method. In this paper, Ni/SiC ceramic coating on carbon steel (45 steel) was made microstructure wear-resistance 45 were studied using scanning electronic microscope (SEM) wear test. results showed that included bonding layer,...
A supersonic plasma sprayed nano-SiC-modified WC/Fe metal–cermet composite coating was remelted with a fibre-pulsed laser at four different scanning speeds (100, 150, 200 and 250 mm·min−1) while the other parameters were kept constant. The microstructures, microhardness, tribological properties of coatings analysed by means SEM (scanning electron microscopy), XRD (X-ray diffractometer), friction tester, respectively. results show that, when speed is 100 mm·min−1, most dense regard to...
