Summary: Additive manufacturing technology is used to process functionally graded materials with high bonding strength, as demonstrated by the successful development of a steel-copper FGM using laser powder bed fusion. X-ray tomography was used to evaluate the low porosity level and the fine dendritic grains in the interface, which contribute to the high interfacial strength. Mechanical and fatigue tests confirmed the ultrahigh bonding strength in FGMs, surpassing that of traditional manufacturing methods, with discussion on the mechanisms involved.

Summary: This paper aimed to design and optimize the structure of a thick thermal barrier coating by adding graded layers for a balance between high thermal insulation capacity and durability. The functionally graded TTBC showed higher durability than conventional TTBC due to improved bonding strength, thermal shock resistance, and lack of a TGO layer at the bond/top coat interface. Additionally, the thermal insulation capacity of the functionally graded TTBC was better than traditional TTBC.

Summary: In this study, the surface features of a porous Ti-23Nb alloy were tailored through thermal oxidation to enhance wear resistance without sacrificing mechanical properties. The results showed that a 6-hour thermal oxidation introduced a 0.5 μm thick TiO2-rutile type oxide layer, resulting in a surface hardness of 620 HV0.025, while a 60-hour thermal oxidation led to a 3.0 μm thick oxide layer and a surface hardness of 980 HV0.025. The alloy with a shorter thermal oxidation duration exhibited slightly better wear resistance and lower friction coefficient compared to the as-sintered state, while the alloy with a longer thermal oxidation duration collapsed at a lower compressive stress.
