These bring with them issues of composite design to join ceramics to metals aiming to combine the advantages of these two kinds of materials.
However, as these materials have dissimilar thermal expansion coefficients, and ceramics possess poor wettability to heterogeneous materials such as metal, the strength of the joint with ceramic to metal is usually insufficient, and their utilization requires gradient to reduce thermal stresses in the materials.
And from the point of view of their application, the variation functionally graded materials can be classified into functional gradient coating, functional gradient joints, and functional gradient material themselves [4].

Wood has many positive properties, but it's no secret that faced with its shortcomings such as fragility, instability of form and susceptibility to decay, people often prefer synthetic materials, putting aside the ecology and useful properties of wood and choosing the long life of non-natural materials.
So, the samples processed in oil were the most resistant of all materials due to the additional impregnation of wood with the treatment agent.
