FGMs generated method SHSM
Journal Title: Archiwum Odlewnictwa - Year 2009, Vol 9, Issue 2
Abstract
In this study, a new SHSF (Self-Propagating High-Temperature Synthesis in Mould) process of synthesis of the functionally gradient materials (FGMs) was described. The said method enabled generating a thin, sub-surface layer of the MMC type in two alloys, i.e. in cast iron/NbC and Ni3Al/NbC systems. The layer was composed of fine-dispersed niobium carbides present in high volume content. The cast iron/NbC and Ni3Al/NbC materials fabricated by the SHSF process were next subjected to metallographic and structural examinations, combined with testing of mechanical properties.

Effect of the concentrated heat flow treatment on the structure and the antiwear properties of cast iron
The influence of modes of surface fusion by electric arc plasma (GTAW method) on the hardness and wear-resistance of plain cast iron was studied. A possible mechanism of structural rearrangement in the processed material...
Application of the Pareto chart and Ishikawa diagram for the identification of major defects in metal composite castings
This author discusses the use of selected quality management tools, i.e. the Pareto chart and Ishikawa fishbone diagram, for the description of composite casting defects. The Pareto chart allows to determine defect prior...
