Determination of the Thermal Expansion of Volume Composite Materials Al–Al2O3, Obtained by the Cold Gas Dynamic Spraying Technology.

This article presents an analysis of the results of a study on a promising method for producing functionally graded composite materials using "cold" gas dynamic spraying technology. In particular, for the Al–Al₂O₃ composite, the influence of the ceramic component content on the change in the coefficient of thermal linear expansion is determined. The results can be used in the design and creation of materials in thermally loaded components to reduce stresses by adjusting thermal gaps. [ABSTRACT FROM AUTHOR]
