- 摘要：
- In this paper, tensile stress distribution in the surface of high-parameter steam turbine blade anti-erosion boride
coatings under single particle impact was investigated using a nonlinear finite element software ABAQUS/explicit
based on the actual erosion environment in power units. The results showed that the single Fe2B phase
coating hardly had stable anti-erosion capability when the coating thickness was less than 20 μm under the
continuous impacts. For the bilayer boride coating composed of top phase FeB and bottom phase Fe2B, the whole
coating began to show the stable anti-erosion performance with top FeB phase coating thickness of 120 μm from
the standpoint of maximum surface tensile stress reduction. Anti-erosion performance of single Fe2B phase
boride coating was 23.15% higher than the bilayer boride coating. Besides, the optimum parameters configurations
for boride coatings were studied.
