1. 5% nano-graphite was added to titanium carbide and its effects on the microstructure and mechanical properties were evaluated.
2. The addition of graphite nano-flakes improved the densification behavior, flexural strength, and friction coefficient of TiC ceramics.
3. Introducing nano-graphite decreased the Vickers hardness of TiC by ~34%, but increased the flexural strength by ~27%.
The article is generally reliable and trustworthy in terms of its content. It provides a detailed overview of the research conducted, including experimental procedure, results, discussion, and conclusions. The article also includes references to other relevant studies which adds to its credibility. However, there are some potential biases that should be noted. For example, the article does not explore any counterarguments or alternative explanations for the findings presented in the study. Additionally, it does not provide any information about possible risks associated with using graphite nano-flakes as an additive for titanium carbide ceramics. Furthermore, it does not present both sides of the argument equally; instead it focuses mainly on the positive effects of adding graphite nano-flakes to titanium carbide ceramics without exploring any potential drawbacks or negative consequences that may arise from this process.
