締結部材の評価:
(1)コーティング
市販のフランジ付きボルトに亜鉛メッキを行い、次いで化成処理(トライバレント1200:(株)JCU製)を行った。このボルトを、実施例11で調製したコーティング剤に浸漬、遠心した後、180℃で20分間焼成した。また、比較として、コーティング剤なしのボルトおよび実施例11で調製したコーティング剤の樹脂成分であるメタアクリル酸アルキルエステル共重合体のみでコーティングしたボルトを準備した。
上記(1)で得られたボルトについて試験例3と同様にして塩水噴霧試験およびその評価を行った。それらの結果を表6に示した。
上記(1)で得られたボルトについて摩擦係数測定装置(岩田鉄工所製)を用い、以下に示した条件にて摩擦係数の評価を行った。それらの結果をあわせて表6に示した。
試験ねじ:フランジ付きボルト
試験速度:3~10rpm
締付方法:指定軸力法
