Spray technology

The coating has to adhere to the substrate. In older thermal spray technology, the bonding may be mechanical as a result of the interlocking between... 

There are job shops and apphcators in the thermal spraying business and the annual value was about 1 x 10 in 1995. Up to 65% of the total company sales represented materials prices from 1— 25 /kg. Equipment prices for spray technology and the number of units sold per annum in the mid-1990s are given in Table 3.

Two major contributions give an excellent view of the development of spray technology plus detailed summaries of current knowledge. Marshall (15A) presents such topics as jet breakup, performance characteristics of atomizers, and drop-size distributions. Miesse (lJfi) traces the theories of jet instability and has performed four series of experiments to verify them.

The behaviour of droplets, as a whole, is a complex area of interest to researchers in a variety of fields, such as combustion, aerosol science and spray technology, to mention a few. Recently, Frohn and Roth have written about many aspects of droplet dynamics and the reader is referred to their book as a good introduction to the subject. However, from an inkjet point of view the researcher is primarily interested in the behaviour of droplets on the substrate, from the moment when the droplet lands to the droplet s end-state. In the first instance, the researcher strives to ensure that droplets land in their specified locations and remain there. Then, they try to control the droplets behaviour in order to obtain the desired morphology. The aim of this chapter is to discuss the lifetime of inkjet-produced droplets from the moment of their impact with the substrate to the moment when the final feature is obtained, which is typically by evaporation of the droplet s carrier solvent or by the solidification of said solvent.

The plasma-spraying technology also allows production of all-ceramic objects, e.g. tubes of wall thicknesses up to about 10 mm and up to 600 mm in length, crucibles for melting precious metals, etc. 

The plasma-spraying technology has been best evaluated and most widely utilized for oxide materials but may also serve for application of high - temperature metals, carbides, borides, nitrides, silicides, etc. Of the non-metallic materials employed in plasma spraying at present, leading position has been gained by AI2O3 possibly modified by further oxides.

An ideal bond coat should have several characteristics that include uncompromised biocompatibility, good adhesion to both the metal substrate and the osseoconductive top coat, and a well-defined melting point to allow application of thermal spray technology. The adhesive function of the bond coat has been loosely compared to the action of a double-sided adhesive tape. 

Surface engineering by thermal spray technologies has attracted increasing attention over the last decades. This book provides the physical background needed to understand the technique and critically assesses its advantages and disadvantages for present and emerging applications.

Plasma spraying is a thermal spray technology in which finely ground metallic and non-metallic materials are deposited on a substrate in a molten or semimolten state (Kudinov et al., 1990 Zhukov Solonenko, 1990 Pawlowski, 1995 Vurzel Nazarov, 2000 Fauchais, Vardelle, Dussoubs, 2001 Fauchais, 2004 Knight, 1991,1998,2005 Yoshida,...
