Mobley, R. K., L. R. Higgins, and D. J. Wickoff, eds. 2008. Maintenance Engineering Handbook, 7th ed. New York McGraw-Hill. This useful reference tool for engineers and technicians performing maintenance covers organization of maintenance, computer applications in maintenance, costs and control, plant, mechanical equipment and electrical equipment maintenance, instrumentation and reliability, lubrication, welding, and corrosion. 

Statistical methods are essential for determining the significance levels of results and corresponding material specifications. Corrosion resistance is only one of many characteristics of a material. Together with the physical, mechanical, and fabrication properties, the corrosion resistance determines the applicability of a material for a specific purpose. These properties may be measured or verified by tests. However, imhke physical and mechanical results, which can be used immediately, corrosion resistance results are often presented in a descriptive or qualitative manner and therefore are difficult to utihze. In order to use the results of these tests for fife prediction, consideration of the methodologies presented in Chap. 4, Modeling, Life Prediction, and Computer Applications, is recommended. 

Projection radiography is widely used for pipe inspection and corrosion monitoring. Film digitisation allows a direct access to the local density variations by computer software. Following to a calibration step an interactive estimation of local wall thickness change based on the obtained density variation is possible. The theoretical model is discussed, the limitations of the application range are shown and examples of the practical use are given. The accuracy of this method is compared to results from wall thickness measurements with ultrasonic devices.

One of the earliest NDT applications for laser-based profilometry systems was for the inspection of marine boiler tubes. Under funding from the U.S. Navy", several systems were developed that were capable of rapidly and accurately mapping the inside surface of 25 mm and 50 mm diameter boiler tubing. Features such as internal pitting and corrosion can be located and quantitatively assessed using computer-graphic analysis. The system employs an... 

The importance of being able to predict the effect of a specific gas analysis on the formation of the corrosive scale is essential in the prevention of blade failures. Again, competent manufacturers have successfully developed a means of achieving this through the application of modern computer programs. However, the gas analysis provided must be as accurate as possible if the program and calculations performed are to have any real value. 

Perfluoropolyethers have a wide range of other specialist applications throughout modern technology ranging from the lubrication of computer discs to lubrication of components in chemical plants exposed to corrosive substances. Their broader usage is limited by their costing typically fifty times as much as conventional hydrocarbon lubricants. 

The most popular application of computers involves programs developed for modeling corrosion and cracking as well as programs for diagnosis, failure analysis and prediction/ analysis. The systems developed are ... 

The types of computer programs which have been applied in corrosion engineering and science fall into categories such as (i) conventional software systems (ii) artificial intelligence and expert systems applications (iii) object-oriented software systems ...

Hiac 2000 liquid particle counter provides an inexpensive means to transfer up to four channels of particle size information data from sensor to host computer system. Data can be viewed in real-time via a liquid erystal display. The 2000 interfaces to all Hiac liquid sensors including the MicroCount, submicron and HRLD laser sensors. Applications include point-of-use monitoring for corrosive chemieal delivery systems, DI water lines, wet process tools, hydraulic oil systems and parts cleaning... 

Other popular alloys of beryllium are those with copper metal. Copper-beryllium alloys contain about 2 percent beryllium. They conduct heat and electricity almost as well as pure copper but are stronger, harder, and more resistant to fatigue (wearing out) and corrosion (rusting). These alloys are used in circuit boards, radar, computers, home appliances, aerospace applications, automatic systems in factories, automobiles, aircraft landing systems, oil and gas drilling equipment, and heavy machinery.

Modern industry users a wide range of electrochemical processes to protect against corrosion, provide surface treatments and to manufacture products. This book focuses on the computer modelling of these industrial processes and techniques by examining the developments of computational models and their application in practice. 

The conference objective was to bring together researchers, engineers and scientist to present and discuss the state of the art in the computer simulation of electrochemical processes and its application in the areas of corrosion, corrosion related fracture and fatigue and coating and deposition processes.
