Cold spray deposition of reduced thermal expansion multiphase materials
Kašuba, Matúš ; Andrew, Ang Siao Ming (oponent) ; Čížek, Jan (vedoucí práce)
The aim of this master’s thesis is to examine and analyze the possibility of adjusting the coefficient of thermal expansion of composite material coatings deposited on substrates by cold spraying. The composite materials in this thesis are represented by powder mixtures, which are prepared by adding a negative thermal expansion phase into the matrix material with positive thermal expansion coefficient. Such cold sprayed materials might be useful for repairs and refurbishment of mechanical components. The cold spray technology is presented in the first part along with its repair and refurbishment applications in engineering industry. Further, thermal expansion behavior of materials is described and the negative thermal expansion phenomenon is introduced. The potential of negative thermal expansion effect in cold spraying is evaluated in the experimental work of this thesis.
