The results demonstrate the feasibility of using wood waste as precursors for the sustainable manufacturing of advanced composite materials, however, optimization of manufacturing parameters and processes should be considered to improve the performance and stability of this material.
The manufacture of these cermets is usually done by sintering at temperatures above 1450ºC [6], a parameter that causes costs to rise enormously and, therefore, the use of these materials is reduced to high performance sectors and not for most common industrial and engineering products where they are also required.
It was initially thought to use natural wood [7][8][9][10][11] since its properties allowed optimizing mechanical resistance versus density, but due to the complexity and heterogeneity in the microstructure depending on the type and cutting area of the tree trunk, makes it a precursor with little possibility of having applications in ceramics and advanced materials where reproducible values are necessary to guarantee the quality of a product.

During welding, temperature distribution of welding area was monitored with K-type thermocouples on the surface of advancing and retreating sides.
The material located at the advancing side is mainly influenced by the friction from shoulder and pin, while at the retreating side, the dominating effects are extrusion and backfill from the advancing side and the shoulder.
It is interesting to note the general trend of higher hardness for the measurements at RS (retreating side) comparing to one at AS (advancing side), which is distinguished at Fig. 4(a).
