2018/11/1Oxidation and oxyacetylene flame tests were performed to evaluate the anti-oxidation and anti-ablation performance of the MoSi 2-CrSi 2-SiC-Si coating. Results showed that the as-prepared coating can withstand long–duration oxidation at low temperature (900 C) for 1320 h and at high temperature (1600 C) for 1190 h with mass gains of 0.06% and 1.24%, respectively.

Influence of Oxidation Degree of Graphene Oxide on Its

Graphene oxide (GO) serves as a versatile platform for various applications, with the oxygen content of GO playing an important role in governing its properties. In the present study, different GO types covering a wide range of oxidation degree were prepared using our newly developed two-step method involving ball milling of graphite followed by its oxidation to GO. In addition to the

Review of oxidant resistant coating on graphite substrate of HTR

2020/1/3The core components of HTR mainly consist of graphite, which is an excellent solid moderating material and structure material with good irradiation performance. However, graphite is easier to be oxidized at high temperature. It is important to improve the anti-oxidation performance of graphite substrate to enhance the safety of HTR. Anti-oxidation coating has been proved that it can

Pd nanoparticles supported on low

Well-dispersed Pd nanoparticles supported on low-defect graphene (LDG) sheets are successfully prepared by a soft chemical method. Our approach can efficiently avoid damaging the graphene framework in the composite because it does not require cumbersome oxidation of graphite in advance and needs no subsequent reduction of the LDG sheets due to the lower oxidation degree.
