润湿角 contact angle
[流] wetting angle
- 并在不同气氛条件下,对镍基粉末在钢表面及石墨表面的润湿角进行了测定;
The contact angle of Nickel Base Powder with steel or graphite surface, was measured in the different atmosphere condition. - 通过建立简化的数学模型,得出了润湿角与钎料熔滴铺展面积间的数学关系式。
The formula that expresses the relationship between the wetting angle () and spreading area (S) has set up by mathematical model. - 结果表明,金属确定后,当润湿角因子不变,晶粒数随着冷却速度的增大而增大,基本呈线性正比关系;
The results show that when the wetting angle factor does not change for a given metal, the quantity of grains increases with increase of cooling rate and has a linear relation.
