Experiments are described to help in understanding the complex abrasion process and in predicting friction and wear behavior in plowing and/or cutting. These experimental modelings and measurements used a single spherical pin (asperity) and a single wedge pin (asperity). Other two-body and three-body abrasion studies used hard abrasive particles.

The tribological properties of chemical-vapor-deposited (CVD) diamond films vary with the environment, possessing a Jekyll-and-Hyde character. CVD diamond has low coefficient of friction and high wear resistance in air but high coefficient of friction and low wear resistance in vacuum. Improving the tribological functionality of materials (such as achieving low friction and good wear resistance) was an aim of this investigation. Three studies on the surface design, surface engineering, and tribology of CVD diamond have shown that its friction and wear are significantly reduced in ultrahigh vacuum. The main criteria for judging whether diamond films are an effective wear-resistant, self-lubricating material were coefficient of friction and wear rate, which must be less than 0.1 and on the order of 10(exp 6) cu mm/N(dot)m, respectively. In the first study the presence of a thin film (less than 1 micron thick) of amorphous, nondiamond carbon (hydrogenated carbon, also called diamondlike carbon or DLC) on CVD diamond greatly decreased the coefficient of friction and the wear rate. Therefore, a thin DLC film on CVD diamond can be an effective wear-resistant, lubricating coating in ultrahigh vacuum. In the second study the presence of an amorphous, nondiamond carbon surface layer formed on CVD diamond by ion implantation significantly reduced the coefficient of friction and the wear rate in ultrahigh vacuum. Therefore, such surface layers are acceptable for effective self-lubricating, wear-resistant applications of CVD diamond. In the third study CVD diamond in contact with cubic boron nitride exhibited low coefficient of friction in ultra high vacuum. Therefore, this materials combination can provide an effective self-lubricating, wear-resistant couple in ultrahigh vacuum.
化学气相沉积(CVD)金刚石薄膜的摩擦学性能随环境的变化而变化，具有双重人格特征。CVD金刚石在空气中摩擦系数低，耐磨性高，在真空中摩擦系数高，耐磨性低。改善材料的摩擦学功能(如实现低摩擦和良好的耐磨性)是本研究的目的。通过对CVD金刚石表面设计、表面工程和摩擦学的研究表明，在超高真空条件下，CVD金刚石的摩擦磨损明显降低。判断金刚石膜是否是有效的耐磨自润滑材料的主要标准是摩擦系数和磨损率，它们必须分别小于0.1和10(exp 6) cu mm/N(dot)m的数量级。在第一项研究中，在CVD金刚石上存在一层薄膜(厚度小于1微米)的非晶、非金刚石碳(氢化碳，也称为类金刚石碳或DLC)，大大降低了摩擦系数和磨损率。因此，CVD金刚石表面的DLC薄膜可以在超高真空条件下作为一种有效的耐磨润滑涂层。在第二项研究中，离子注入在CVD金刚石表面形成非晶态的非金刚石碳层，显著降低了超高真空条件下的摩擦系数和磨损率。因此，这种表面层是可以接受的有效的自润滑，CVD金刚石耐磨应用。在超高真空条件下，与立方氮化硼接触的CVD金刚石具有较低的摩擦系数。因此，这种材料组合可以在超高真空条件下提供有效的自润滑、耐磨偶。

A revolution in diamond technology is in progress as the low-pressure process becomes an industrial reality. It will soon be possible to take advantage of the demanding properties of diamond to develop a myriad of new applications, particularly for self-lubricating, wear, and superhard coatings. The production of large diamond films or sheets at low cost, a distinct possibility in the not-too-distant future, may drastically change tribology technology, particularly solid lubricants and lubricating materials and systems. This chapter reviews the structures and properties of natural and synthetic diamond to gain a better understanding of the tribological properties of diamond and related materials to be described in the following chapters. Atomic and crystal structure, impurities, mechanical properties, and indentation hardness of diamond are described.
