Direct current bias applied to hot flame diamond deposition produces smooth low friction coatings

As-deposited diamond coatings generally have a high surface roughness which results in a high friction coefficient and extensive wear of the counter material in sliding contact. Therefore several methods for smoothening diamond coatings have been proposed, such as laser polishing, molten metal etching, thermochemical polishing and mechanical polishing. All these methods have some disadvantage e.g. long processing time or high processing temperature. Furthermore, they are all post-deposition treatments i.e. the manufacture of these coatings requires at least two processing steps, deposition and smoothening. With the present method which combines d.c. bias with hot flame diamond deposition, a smooth diamond surface is produced during the actual growth of the film. No post-deposition treatment is necessary. The surface roughness is not dependent on the coating thickness which means that thick coatings with smooth surface can be produced. In fact, the method has a smoothening effect, i.e. rough surfaces can be made smooth. The method is comparable to conventional hot flame deposition of diamond as to growth rate and cost of producing the coatings. The coatings have a nano-crystalline structure and a surface roughness of Ra = 25 nm, and result in a friction coefficient of 0.1 or less in dry sliding and about 0.05 in water-lubricated sliding against cemented carbide. Their wear resistance is virtually the same as that of conventional diamond films.

中日输电线路设计标准中有关导线布置的对比

为了避免在参与国际市场竞争中因不同国家输电线路设计标准对导线布置要求不同而对我国电力企业线路设计、施工造成障碍,从水平线间距离、垂直线间距离和最小水平位移等方面对《110kV～750kV架空输电线路设计规范》（以下简称中国标准）与《日本架空送电线路绝缘设计纲要》（以下简称日本标准）中的导线布置进行对比,探讨2个标准在导线布置设计过程中的思路和取值。采用中、日标准分别进行水平线间距离算例分析,结果表明,在电压等级低时,中、日两国标准的设计参考值相差不大;电压等级较高时,日本标准比中国标准的设计参考值要大,且随着电压等级越高,该差值越大。
