Sprayed coatings mechanical properties

By examining the dispersion properties of surface acoustic waves, the layer thickness and mechanical properties of layered solids can be obtained using the SAM. It can be used to analyze the wear damage progress [104], and detect the defects of thermally sprayed coatings [105]. 

Plasma-sprayed, flame-plated, or electrolytically deposited coatings of powders of Al O Ci O TiN, WC, and Ti02 can be applied as wear-resistant ceramics on metal substrates with or without Co, Ni, or Cr incorporated to improve mechanical properties. Silver, barium fluoride—calcium fluoride, and other modifying materials have also been found useful in ceramic coatings for improved friction and wear properties (35). Diamond coatings are also being developed (36). 

To achieve the main process requirements (ability to be applied by different methods by hand, spray, electropaint), and to provide the necessary decorative, physical, and mechanical properties, organic solvents are used in concentrations up to of about 50% to modify the viscosity and other rheological characteristics of the some polymer compositions. During the application and formation of the coating, the solvents evaporate into the atmosphere as pollutants. This serious disadvantage of formulations based on the use of solvents as "intermediate" carriers has provided the incentive to develop polymer compositions and application technologies which yield the required rheological characteristics either without solvents, or at least with low concentrations of them.

Ca(OH)2, respectively. The mechanical properties of the deposits such as critical load, scratch hardness and friction coefficient were determined by scratch testing under loads of 3-9 N. The coatings sprayed onto titanium alloy indicated critical load of 12.3 N and the ones onto aluminium substrate were lower and equal to 10.5 N.
