実施例1−耐食性の向上
実験を60×60×3mmの炭素鋼板上で実行した。5枚のプレートの表面を酸化亜鉛粉末のみを用いて前処理し、5枚の他のプレートの表面を、以下の粉末の混合物で処理した:30%(質量)の酸化亜鉛、および70%の金属亜鉛粉末。両方の種類のサンプルを、10分間30℃で、同じリン酸亜鉛コーティング液中でコーティングした。
リン酸亜鉛および亜鉛−リン酸亜鉛の複合コーティングを備える5つのサンプルそれぞれの2つの類似の群を、2層の粉末コーティングによりコーティングし:ここで、第1の層はエポキシであり、上部の層はポリエステルである。そのサンプルを、引張強さに関して試験した。図5は、革新的な複合リン酸塩コーティングを用いてコーティングされた炭素鋼板である試験サンプルから、付着部材を剥がした後の試験サンプルの画像である。付着力は、19.13MPaとして記録される。両方の群中の全てのサンプルに対する付着の値は、19から23MPaまで変動した。すべての試験において、塗料コーティング界面(paint coating interface)における不良は1つもなかった。試験の結論は、亜鉛−リン酸亜鉛複合コーティングは、リン酸亜鉛コーティングのように、同じような粉末塗料付着率を有するということである。
50mmの直径および6mmの厚さを有する炭素鋼ディスク上で、実験を実行した。5枚のディスクの表面を酸化亜鉛粉末のみを用いて前処理した一方、別の5枚のディスクの表面を、以下の粉末の混合物で処理した:45%(質量)の酸化亜鉛、35%の金属亜鉛粉末、および乾燥した潤滑剤としての、20%の二硫化モリブデン(MoS2)粉末。両方のサンプル群を、10分間30℃で、同じリン酸亜鉛コーティング液中でコーティングした。1%(質量)の界面活性剤を、リン酸塩コーティング液に添加した。サンプルの第1セット(酸化亜鉛のみ)上に形成されたリン酸亜鉛化成コーティングは、15±2g/mlの重量を有していた。サンプルの第2セット上に形成された複合MoS2−亜鉛−リン酸亜鉛コーティングは、15±3g/m2の重量を有していた。この複合コーティングの表面を走査型電子顕微鏡(SEM)で評価した。図6は、複合MoS2−亜鉛−リン酸亜鉛コーティングのSEM画像である。リン酸亜鉛コーティング上に固定されたMoS2粉末粒子を見ることができる。
有機、無機のいずれか、またはその両方の着色顔料を、酸化亜鉛粉末と混合することもある。好ましい実施形態において、約3%から15%(質量)の範囲の顔料を、顔料のタイプに応じて添加する。その顔料は、前処理したものに、および/またはリン酸塩コーティング液へと添加されうる。
