Corrosion and fretting wear behavior of Cr-based composite coatings on zirconium alloy
The accident tolerant fuel (ATF) was developed to improve nuclear safety and economic benefits of nuclear power after the Fukushima nuclear accident. The coatings prepared on zirconium (Zr) alloy fuel cladding is one of the primary research directions for ATF. In this research, Cr, CrN, Cr/CrN/CrAlN (Multi-1), and Cr/CrN/CrAlN/CrAlSiN (Multi-2) coatings were prepared on Zr alloy using magnetron sputtering technology. The characteristics, corrosion, and fretting wear behavior of different coatings were investigated. The results show that different coatings can improve the corrosion resistance of Zr alloy, and Cr coating has the best corrosion resistance in high-temperature pressurized steam condition because a very thin Cr2O3 layer is formed on the surface after corrosion, effectively preventing the penetration of oxygen ions. Zr alloy exhibits the significant wear damage, primarily including adhesive wear, abrasive wear, and oxidative wear. The CrN coating presents the best wear resistance compared with other coatings. The wear depth, wear area, and wear rate of CrN coating are 1/4, 1/3, and 1/8 of Zr alloy, respectively. The wear mechanisms of different coatings predominantly involve abrasive wear and oxidative wear. Based on the above results, CrN coating has both the best wear resistance and good corrosion resistance.
期刊介绍：
Vacuum is an international rapid publications journal with a focus on short communication. All papers are peer-reviewed, with the review process for short communication geared towards very fast turnaround times. The journal also published full research papers, thematic issues and selected papers from leading conferences.
A report in Vacuum should represent a major advance in an area that involves a controlled environment at pressures of one atmosphere or below.
The scope of the journal includes:
1. Vacuum; original developments in vacuum pumping and instrumentation, vacuum measurement, vacuum gas dynamics, gas-surface interactions, surface treatment for UHV applications and low outgassing, vacuum melting, sintering, and vacuum metrology. Technology and solutions for large-scale facilities (e.g., particle accelerators and fusion devices). New instrumentation ( e.g., detectors and electron microscopes).
2. Plasma science; advances in PVD, CVD, plasma-assisted CVD, ion sources, deposition processes and analysis.
3. Surface science; surface engineering, surface chemistry, surface analysis, crystal growth, ion-surface interactions and etching, nanometer-scale processing, surface modification.
4. Materials science; novel functional or structural materials. Metals, ceramics, and polymers. Experiments, simulations, and modelling for understanding structure-property relationships. Thin films and coatings. Nanostructures and ion implantation.
