三、根据步骤二的配方将上述的镍基粉与胶水在温度控制在70~80℃中混合成混合料,并将混合料搅拌至均匀;所述胶水的加入到镍基粉的加入量为镍粉重量的9~11%,所述百分比为重量百分比;
四、选取具有设定强度的拉线,在拉线上均匀地粘上金钢砂,备用;
五、将温度为70~80℃的混合料,放入温度控制在70~80℃的机筒内腔中,在机筒两端的内腔中分别放置圆形模架,所述圆形模架外周面与对应机筒内壁的圆周面之间分别形成圆环形空腔;将涂有金钢砂的拉线穿于机筒两端的圆环形空腔中,拉线的两端分别延伸出机筒两头,将延伸出机筒两端拉线头以圆环形空腔同步作圆周运动,周时机筒通过传动装置作慢速转动,位于机筒内腔中混合料通过拉线和机筒的转动被均匀地涂于机筒的内壁上,涂于机筒内壁混合料的厚度为机筒内壁与圆形模架外周之间少一线的距离;
六、将涂有混合料的机筒置于真空炉中加温至1060~1068℃,保温7~8小时,然后待自然冷却至69~71℃,再将温度为69~71℃的机筒置于350~450℃的真空炉中回火2~3小时;
七、将回火后的机筒从真空炉中取出,然后再经抛光处理,即制成内壁有耐磨层的耐磨机筒。
作为改进,所述步骤五中的慢速转动的转速可选择为2~3转/分钟。
作为改进,所述胶水可优选为油性胶水。
作为改进,所述油性胶水是将丙烯酸或聚氨酯溶解于甲苯或丁酮中的油性胶水。
