Available in PDF, EPUB and Kindle. Book excerpt: In most tribological applications, liquid or grease based lubricants are used to facilitate the relative motion of solid bodies to minimize friction and wear between interacting surfaces. The challenges for liquid lubricants arise in extreme environmental conditions, such as very high or low temperatures, vacuum, radiation, and extreme contact pressure. At these conditions, solid lubricants may be the alternative choice which can help to decrease friction and wear without incorporating liquid lubricants. Challenges with solid lubricants are to maintain a continuous supply of solid lubricants on the contact surfaces to act as lubricous layer between two sliding surfaces. Such a continuous supply is more easily maintained in the case of liquid lubricants when compared to solid lubricants. The most innovative development to ensure a continuous supply of solid lubricant to the contact surface during sliding is to introduce solid lubricant as reinforcement into the matrix of one of the sliding components. Composite materials are engineered or naturally occurring materials which contain two or more distinct constituents with significantly different chemical, physical and mechanical properties. Composites consist of reinforcement and matrix (metal, polymer and ceramics). Among various reinforcements, recent emerging material, solid lubricant, is found to have many favorable attributes such as good lubrication property. Self‐lubrication is the ability of a material to provide lubrication to the contact surface to decrease friction and wear rate in the absence of an external lubricant by transferring embedded solid lubricants in the composite to the interface. Self-lubricating composites (SLCs) are an important category of engineering materials that are increasingly replacing a number of conventional materials in the automotive, aerospace, and marine industries due to superior tribological properties. In SLCs, solid lubricant materials, including carbonous materials, molybdenum disulfide (MoS2), and hexagonal boron nitride (h-BN) are embedded into the matrices as reinforcements to manufacture a novel material with attractive self-lubricating properties. Several studies have been investigated the tribological properties of self-lubricating materials. This book fills that gap to have a reference book about self-lubricating materials and their properties to help scientists, engineers, and industries. This book discusses mechanisms of self-lubricating materials, self-lubricating properties and the applications for industries. The chapters will be written by authoritative expertise in the field. Additionally, this book will demonstrate fundamental study and most advanced innovations in self-lubricating materials as regards to friction and wear. The chapters also include tribological properties of composites and coatings and some practical applications of self-lubricating materials.

Available in PDF, EPUB and Kindle. Book excerpt: A tribological assessment of non-conventional solid lubricant coatings or concepts for space application is done. Solid lubrication in terms of coatings in space is dominated by Molybdenum Disulfide (MoS2) based coatings which are sensitive to testing and storing environment (ambient conditions) as well as wear out easily under heavy load applications due to their soft nature. Thus, there is a need for alternative solid lubricants which possess high inertness and good wear resistance. The main purpose of the assessment in this work involves screening of alternative potential candidates other than MoS2 based solid lubricants for spacecraft systems or space applications. Various sources of carbon (DLC) and polymer (PTFE) based solid lubricant coatings are tested using pin on disc tribometer under vacuum and ambient conditions. Endurance and ambient tests are carried out only for well performed DLC solid lubricant coatings. Additionally, tribological assessment is done on modified and unmodified surfaces in order to verify enhanced lubrication effect and surface hardening. The lubrication effect is examined using untextured and laser textured Ti6Al4V surface lubricated with MoS2 solid lubricant. The surface hardness effect is tested using plain machine hammer peened steel and machine hammer peened steel embedded with tungsten carbide hard particle. Tribological properties such as friction and wear rate are investigated in both cases. Physical analysis of the coating and textured surfaces is carried out using Leica 3D optical microscope for determining the wear rate. Chemical analysis is made using X-ray photoelectron spectroscopy only for best performed DLC coatings to analyse the formation of lubrication layer at the interface between pin and disc. Combination of surface texture and solid lubricant provided two fold reduced friction coefficient than the untextured but for only very limited period of time. On the other hand, improvement in surface hardness is observed by embedding hard particles on machine hammered steel. Tribological tests and post analysis indicated that few DLC coatings have provided low and steady-state friction coefficient than PTFE and MoS2 under vacuum environment. But, life time of the DLC coatings are poor in vacuum when compared to the tested PTFE and MoS2 coatings in this project.*****A tribological assessment of non-conventional solid lubricant coatings or concepts for space application is done.

Book excerpt: Lubrication of Electrical and Mechanical Components in Electric Power Equipment presents an analysis of multiple applications of lubricants in the power industry for both electrical and mechanical parts. One of the key features of this book includes a look at the use of lubricants for surfaces of electrical and mechanical parts protection from mechanical wear and friction. Also included are examples of degradation due to fretting, as well as corrosion protection when lubricant is a barrier between metallic surfaces and atmospheric pollutants. This book analyzes the effects of chemical composition and consistency (fluids, greases, solid lubricants) and the durability of lubricants in regard to various types of contacts and mechanical parts material, design and load. Focused on the importance of carefully choosing the lubricants to maintain a stable contact resistance; preserve the physical integrity of the contact surface; and extend the useful life of mechanical parts, such as bearings, the author presents an exhaustive list of lubricants manufacturers and products recommended for use in the electrical industry.
