Tensile test method for micro-colis of ceramic fibers.

Vapour Growth of Micro-Coiled Ceramic Fibers and their Properties

Micro-coiled fibers of carbon, Sic, Si N Tic, ZrC and Hf C were prepared by a metal-impurity activa?e%'chemical vapor deposition or vapour phase metallizing of the coiled carbon fibers. The growth conditions, morphology, growth mechanism and some properties were examined. The double-coiled carbon fibers were prepared using acetylene as a carbon source and various powders or plates of transition...

deoxyuridine suppression test . New micro method for

The deoxyuridine suppression (dU) test measures the effect of deoxyuridine in suppressing the uptake of radioactively labelled tritiated thymidine into DNA and is specifically abnormal in vitamin B12 or folate deficiency, or when the metabolism of these is disturbed. The test is based on the observation that bone marrow cells from patients deficient in vitamin B12 incorporated much more thymidi...

Effect of curing and silanizing on composite repair bond strength using an improved micro-tensile test method

Objectives: To evaluate the micro-tensile repair bond strength between aged and new composite, using silane and adhesives that were cured or left uncured when new composite was placed. Methods: Eighty Filtek Supreme XLT composite blocks and four control blocks were stored in water for two weeks and thermo-cycled. Sandpaper ground, etched and rinsed specimens were divided into two experimental g...

MICRO-EDM FOR MICRO-CHANNEL FABRICATION ON NONCONDUCTIVE ZrO2 CERAMIC

In this study, microelectro-discharge (micro-ED) milling of nonconductive ZrO2ceramicsis investigated using a Cu tool electrode in kerosene dielectric. An adhesive Cu foil is firmly attached on the workpiece to initiate the sparks. After the machining of Cu foil, an electrically conductive carbonic layer is formed on the ceramic workpiece disassociating the kerosene dielectric, which allows mic...
