一、喷丸强化工艺因素的选择喷丸强化过程有许多因素,直接影响零件的喷丸强化效果。比如,弹丸的直径、速度、流量、喷嘴与被喷零件之间距离、喷射角度和喷丸时间的选择。 1.喷丸的选择弹丸是喷丸强化的介质,常用材料有铸铁,钢和玻璃丸三种。选择弹丸首先应具备圆球形状,其次在具有一定冲击韧性条件下,硬度越高越好。经常使用的直径为0.05～1.5毫米,铝合金采用直径不大于0.3毫来的玻璃丸;对表面光洁度要求较高的零件,应采用较小的玻璃弹丸;对小模数
First, the choice of peening process factors Peening process has many factors that directly affect the parts of the shot peening effect. For example, the diameter of the projectile, velocity, flow rate, the distance between the nozzle and the part being sprayed, the spray angle and the shot peening time. Shot peening projectile is shot peening medium, commonly used materials are cast iron, steel and glass pill three. Select projectile should first have a spherical shape, followed by a certain impact toughness conditions, the higher the better hardness. Often used diameter of 0.05 to 1.5 mm, aluminum alloy with a diameter of not more than 0.3 millimeters of glass balls; for the surface finish of the higher parts require the use of smaller glass projectile; small modulus
