Book Description
An experimental study was conducted on the twin-wire electric arc spraying of aluminum coatings. This aluminum wire system is being used to fabricate heater tubes that emulate nuclear fuel tubes for use in thermal-hydraulic experiments. Experiments were conducted using a Taguchi fractional-factorial design parametric study. Operating parameters were varied around the typical process parameters in a systematic design of experiments in order to display the range of processing conditions and their effect on the resultant coating. The coatings were characterized by hardness tests, optical metallography, and image analysis. The paper discusses coating qualities with respect to hardness, roughness, deposition efficiency, and microstructure. The study attempts to correlate the features of the coatings with the changes in operating parameters. A numerical model of the process is presented including gas, droplet, and coating dynamics.

Book Description
This fully revised, industry-standard resource offers practical details on every aspect of the fundamentals necessary for understanding thermal spray technology, from powder all the way to the final part. The second edition is presented in a reader-friendly format that is split into four parts. Part I presents a review of thermal spray coating and its position in the broad field of surface modification technologies. Highlights of combustion and thermal plasmas are given with an expanded treatment of in-flight plasma-particle interactions. The second and third parts deal respectively with an updated presentation of thermal spray technologies and coating formation, including solution and suspension plasma spraying. The last part of the book includes a comparative analysis of different thermal spray processes, which is essential for the optimal selection of the appropriate thermal spray process in a given application. Coverage of system integration has been expanded with the addition of a detailed discussion of online instrumentation and process diagnostics and numerous examples of industrial scale spray booth designs. Attention is also given to coating finishing and health and safety issues. An extensive review is presented of thermal spray applications grouped in terms of process objectives and present use in different industrial sectors. This book will serve as an invaluable resource as a textbook for graduate courses in the field and as an exhaustive reference for professionals involved in the thermal spray field.

Book Description
To study the effect of impact velocity and substrate temperature have on splat morphology, aluminum wire was sprayed, using the ValuArc 100 wire arc spray gun, onto polished AISI304L coupons held at various temperatures. In-flight particle parameters (size, velocity, temperature) were measured using a DPV 2000 system. Individual splats deposited on the substrate were photographed. Comparisons between the in-flight particle size distribution and the final splat size distribution showed that increasing substrate temperature results in increased mean spread factor. A transition temperature from splash to disk splats was determined. Experiments also showed that increasing substrate temperature was found to improve both deposition efficiency and adhesion strength. Coatings were also produced at various substrate temperatures and porosity levels measured. Analysis of the coating microstructure showed that increasing the substrate temperature helps to reduce voids at the substrate/coating interface. Porosity levels were measured to be less than 5% in all cases.
