thermal shock test
Examples
- Thermal shock test for toughened glass insulator
热震试验对钢化玻璃绝缘子 - 3d - c / sic fabricated with t300 carbon fibers weaved into 3 - dimensional and 4 - directional structure , was deposited pyrocarbon and sic matrix at 950 - 1000 with cvi method . fiber volume fraction of 3d - c / sic was 40 - 45 % , composite density was 2 . 01g / cm3 and porosity was 17 % . in addition , the thickness of pyrocarbon interface was 200 nm for interaction fatigue - creep ; the interface layer of pyrocarbon for thermal shock had three thickness obtained by controlling deposition time which were 10h , 20h , 30h , respectively
3d - c sic是用t300碳纤维编织成三维四向编织体， cvi法在950 - 1000致密，纤维体积分数为40 - 45 ，密度为2 . 01g cm ~ 3和孔隙率为17 ，用于疲劳蠕变交互作用试验热解碳界面层厚度约0 . 2 m ；用于热震试验的有三种界面层厚度分别是热解碳沉积时间10小时、 20小时、 30小时获得。 - The pretreatment , effect of bath compositions and operation conditions such as temperature , currenty and time on compactness of the zinc and cu / ni / cr coatings have been investigated . the relationship of operation conditions to thickness of the coatings was studied by weight method . the specimens have been pickled in nacl or sulfate acid solution to evaluate the porosity of the coating
研究了镁合金电镀前处理工艺,电镀锌、电镀铜/镍/铬工艺配方及其施镀温度、电流密度和时间对镀层致密性的影响;采用称重法研究施镀工艺与镀层厚度的关系,利用nacl溶液和硫酸溶液浸泡试样来考察镀层孔隙率,采用划痕试验和热震试验检验镀层的结合力,采用金相显微镜和扫描电子显微镜观察镀层表面形貌。
