Fractals can be extremely useful when applied to tribology. Obtaining fractal descriptions of engineering surfaces and wear particles requires surface topography information to be measured, digitized and processed. Such procedures can be rigorous. This article compares various methods to calculate profile and surface fractal dimension. Profile fractal dimension is computed using three available methods, corresponding to the yard-stick, the power spectrum and the structure function method. The precision of the three methods is analyzed and compared in this paper. Surface fractal dimension is calculated using the slit island and the box counting method. Both profile fractal dimension and surface fractal dimension are used to describe TiN coating surfaces and wear particles.

Six sliding wear tests have been conducted using a pin-on-disc tester to investigate the effects of temperature on sliding wear processes when the iron particle contaminants were existent or non-existent in the SAE40 lubricant. Ferrography analysis, particle size analysis using a CSI particle analyzer, numerical analysis on particle morphology based on confocal laser scanning microscope (CLSM) and surface examination of the tested samples using scanning electron microscope (SEM) were used to study the wear particles and the wear surfaces. Supported by data generated from the comprehensive analyses of the wear particles and the surfaces of the tested samples, it is clear that the temperature of the SAE40 lubricating oil has a significant influence on the wear processes. The increase in the temperature of the SAE40 lubricant increases the probability of adhesion, oxidation and wear rates. For the tests at elevated temperature, when the iron particles are added into the SAE40 lubricant, the degree of oxidation wear increases compared with the test without the iron particles in the SAE40 lubricant. This study has shown that temperature plays an important role in wear process and it is crucial to control temperature for controlling wear rates in sliding wear process.

在磨粒分析研究领域，磨粒二维特征研究已经比较成熟，但是根据二维图像无法准确获取磨粒表面的三维形貌信息，磨粒的三维图像能给研究者提供更完全更丰富的信息，因此，开展磨粒的三维表面形貌研究具有重要意义。欲开展磨粒的三维研究，首要的难题是磨粒表面高度数据的获取。激光共焦扫描显微镜（CLSM）及其图像处理技术的发展为获取磨粒的三维表面信息提供了契机。研究开发了基于Bio-rad Radiance 2000激光共焦显微镜的磨粒三维表面形貌获取技术，结果表明具有良好的应用效果。
