Matter high-strength temperature-resistant impingement.
Background technology
In recent years, with the fast development of the extreme environment field of detecting such as deep space, deep-sea, deep, the pass in high-end devices
The working-blade of key member, such as engine, the turbine disk, combustion chamber, the active demand base part have concurrently lightweight, high-strength feature and
The performances such as heat shock resistance, resistance rupture failure, this also turns into the study hotspot of domestic and foreign scholars extensive concern.But at present
Apply the field related keyword part majority only have high-strength light characteristic and generally existing thermal shock resistance difference lack
Fall into, thus have become the bottleneck of such equipment Development.
And the biology of nature provides new approaches for the solution of this problem.The rifle shrimp lived in ocean, Ke Yitong
Quick-make chela portion is crossed, cavitation bubble is produced and prey moment is hit dizzy or shot dead.Research shows, when rifle shrimp moment quick-make chela
During portion's offensive attack, the water body that can impact periphery produces bubble.These bubbles are under the pressure of surrounding water apart from chela portion tip
Instant exploding occurs about at 3mm, produces cavitation, and then produce 4500-4700 DEG C of high temperature.Chela portion quickly closing in water
