It is shown that the erosive resistance at high angle of impact is wrose than at low angle regardless of austenite or martensite matrix;
结果认为无论马氏体基体还是奥氏体基体，高角度冲击下的耐磨性都低于低角度冲击；
On both sides of the bluff-body there exists high concentration and the airflow impact the bluff-body with a certain angle, which causes severe erosion of the two sides of the bluff-body.
在钝体两侧煤粉浓度比较大，且气流以一定角度冲刷，因此在钝体两侧煤粉对其冲刷严重，磨损加剧。
