Description
1.5mmの低炭素鋼(SPCE)上に、Cu−6質量%Sn−0.1質量%Pの青銅合金粉末(-60メッシュ)を散布後、還元性を有する焼結炉にて950℃で15分焼結し、冷却後、圧延ロールにて乾式圧延を施し、再度同条件で焼結し空孔率3%、厚さ0.35mmの青銅合金層と厚さ1.35mmの低炭素鋼との複層材を得、その後、その複層材を圧延ロールにてロール表面に圧延油(パラフィン系原油から生成された鉱物油)を供給しながら湿式圧延を行った。この際の圧延率はロール表面と複層材表面との微視的焼付が起こらない限界の圧延率(表1に示す。)とした。その後、絞り加工を行うために、還元性を有する焼結炉にて810℃で15分アニールして実施例1を得た。
複層材を得るまでの工程は、実施例1と同じであるが、その後の複層材の圧延工程が乾式圧延で行ったものである。この際の圧延率はロール表面と複層材表面との微視的焼付が起こらない限界の圧延率(表1に示す。)とした。その後、絞り加工を行うために、還元性を有する焼結炉にて810℃で15分アニールして比較例1を得た。
複層材を得るまでの工程は、実施例1と同じであるが、その後の複層材の圧延工程が乾式圧延で2回行ったものである。この際の圧延率はロール表面と複層材表面との微視的焼付が起こらない限界の圧延率(表1に示す。)とした。ただし、2回の乾式圧延の間に還元性を有する焼結炉にて810℃15分のアニールを行っている。その後、絞り加工を行うために、還元性を有する焼結炉にて810℃で15分アニールして比較例2を得た。
複層材を得るまでの工程において、青銅合金層の空孔率が4%である点を除いて実施例1と同じであるが、その後の実施例1と同じように、複層材を圧延ロールにてロール表面に圧延油(パラフィン系原油から生成された鉱物油)を供給しながら湿式圧延を行った。この際の圧延率はロール表面と複層材表面との微視的焼付が起こらない限界の圧延率(表1に示す。)とした。その後、絞り加工を行うために、還元性を有する焼結炉にて810℃で15分アニールして比較例3を得た。

Claims (3)
- 鋼裏金上に青銅合金を散布し焼結して得られた多孔質青銅合金層の空孔率を乾式圧延工程と焼結工程とを施して空孔率3%以下の青銅合金と鋼との複層材を得た後、該複層材に対し圧延ロール表面にパラフィン系潤滑油からなる圧延油を供給して行う湿式圧延工程を施し、該湿式圧延工程を施した後、アニール熱処理工程を施すことを特徴とする青銅合金と鋼のクラッド材の製造方法。
