In the " Diamond Club Online ", besides the exciting facilities and functions mentioned above, its services are all diamond grade. 《钻石俱乐部Online》除了上述令人心动的设施与功能之外,在服务上也是钻石级(DG)的!
In this paper, the influence of structural features of diamond such as size, shape, surface and inclusion on strength and thermal stability of synthetic diamond is discussed. Diamond grade partition is studied on the basis of the contents discussed above. 讨论了金刚石颗粒尺寸、形状、表面状况以及包裹体等结构特征对其强度、热稳定性等性能的影响,并对人造金刚石的品级划分进行了探讨。
Trie formula gave reasonable technical parameters such as diamond grade, its grit size, thermal stability and concentration for making diamond scraping wheel. The Craft of Strong Wheel Gear Scraping 在得到的金刚石参数间关系公式的基础上,讨论了刮轮刀头胎体和金刚石质量、浓度、粒度的设计思路和方法,制造的金刚石刮轮在实际生产使用中效果比较理想。硬齿面刮削工艺
A comparison of the diamond saw blade using ordinary diamond with that using Ti-plated diamond reveals that the desquamating grade of diamond reduces from 72.2 % to 32.3 %, representing a decrease of 39.9 %; 使用一般金刚石与使用熔盐镀Ti金刚石的金刚石锯片相比,金刚石的脱落度由72.2%降至32.3%,减少39.9%;
Finer diamond can be used partly as substitute of coarse ones, or even a fraction smaller size can be adopted, which can reduce the cost with better performance especially for drilling medium to hard formation ( grade 8-10 ); 可以适当采用部分细粒度的金刚石替代粗粒度,甚至可以细一个粒度级,在降低成本的同时也能取得较好的效果,特别是在中硬地层(8~10级)钻进时效果尤其明显;
