Tribology and Surface Engineering

Tribology in Reliability Engineering

The tribological understanding of friction and wear mechanisms and the generation of reliable friction and wear data are of increasing importance for the determination of reliability of machinery and availability of plants and transportation systems. To be of real value in reliability engineering, the tribological data should be expressed in terms of endurance life and probability of failure. T...

Surface Chemistry in Tribology

Introduction In general, the twentieth century marked the first major incursion of chemists into the world of tribology. Driven partly by the need for improved lubricants for new machines developed in the first few decades of the century, and partly by new analytical capabilities, lubricant chemists and tribochemists were to become full partners in the science of tribology. In this review we co...

Fuzzy contact and interface temperature in engineering tribology

The contact behaviour between the grinding wheel and workpiece in abrasive machining processes has been investigated. This has revealed the ambiguity in deciding the size of the contact region from a measured contact signal. For improved representation of the contact conditions, fuzzy set theory was used. A membership function for the fuzzy representation of the extent of wheelworkpiece contact...

Railway Open System Tribology Railway Open System Tribology

Tribology in the railway system is of increasing interest in the new railway era due to the demand for higher speed and load capacity. Since railway vehicles operate in an open environment, their performance depends greatly on temperature, humidity and natural and artificial contaminants. Meanwhile, the “feedback” of railway vehicles to the surroundings, such as noise and airborne particles, is...
