Ceramic industrial kiln refers to the combustion equipment for ceramic production, which generally roller kiln, shuttle tunnel and kiln. Roller with continuous firing rotating as vehicle of billet body; Tunnel adopts takes rail car transport body. Shuttle is fired intermittently consists car, chamber door. Factors influencing energy saving include construction materials, structure, technology, ...

Co-Continuous Ceramic Composites, referred to as C4, have bi-continuous, interconnected and interpenetrating phases of a metal and ceramic. This bestows such composites with a higher strength to weight ratio compared with traditional composites. In this research work, a C4 composite of AA5083/SiC is fabricated for personal body armour, using gravity infiltration technique. A numerical simulatio...

BACKGROUND Material wear testing is an important technique in the development and evaluation of materials for use in implant for total knee arthroplasty. Since a knee joint induces a complex rolling-gliding movement, standardised material wear testing devices such as Pin-on-Disc or Ring-on-Disc testers are suitable to only a limited extent because they generate pure gliding motion only. METHO...

The wear resistance of denture teeth is important to the longevity of removable prostheses of edentulous patients. The ability of denture teeth to maintain a stable occlusal relationship over time may be influenced by this property. The purpose of this in vitro study was to evaluate the wear resistance of polymethyl methacrylate (PMMA) denture teeth based on their chemical composition when oppo...

A new tool based on artificial neural networks (ANNs) has been developed for the design of lightweight ceramic metal armours against high velocity impact of solids. The tool devel oped predicts, in real time, the response of the armour: impacting body arrest or target perforation are determined and, in the latter case, the residual mass and velocity of the impacting body are determined. A large...

In 1960s, toxic heart failure due to cobalt poisoning was firstly reported from Canadian industrial worker. Following development of bearing materials in hip arthroplasties, using cobalt-chrome alloy in bearing surface, there were rarely reported of systemic affect toxic cobaltism include toxic heart failure due to articulation wear in Western countries. It could be happened more easily by thir...

objectives : microbial leakage through the implant-abutment (i-a) interface results in bacterial colonization in two-piece implants. the aim of this study was to compare microleakage rates in three types of replace abutments namely snappy, goldadapt, and customized ceramic using radiotracing. materials and methods: three groups, one for each abutment type, of five implants and one positive and ...
