Abstract
【解決手段】本発明は、3価クロム濃度が0.01〜100g/Lの範囲であり、亜鉛、コバルト、ニッケル及びその組み合わせからなる群から選択される金属の濃度が0.01〜100g/Lの範囲であり、フッ素濃度が0.01〜50g/Lの範囲であり、かつ6価クロムを含有しないアルミニウム又はアルミニウム合金用3価クロメート液を提供する。
Description
このような中、アルミニウム及びアルミニウム合金には、耐食性や塗料との密着性向上を目的として6価クロメート処理等の表面処理が施されている。しかしながら、上記6価クロメート処理は、主成分として6価クロムを使用しているため、処理液はもちろんのこと、6価クロメート皮膜にも6価クロムが含まれている。この6価クロムは人体や環境に悪い影響を与える事が指摘されており、最近では、6価クロムの使用を規制する動きが活発になってきている。
その代替技術の一つとして3価クロムを使用した6価クロムフリーの表面処理方法が開示されているが(例えば、特許文献1から4参照)、6価クロメート並みの十分な耐食性及び塗料との密着性を有しておらず、工業化されていないのが現状である。
従って、本発明は、3価クロム濃度が0.01〜100g/Lの範囲であり、亜鉛、コバルト、ニッケル及びその組み合わせからなる群から選択される金属の濃度が0.01〜100g/Lの範囲であり、フッ素濃度が0.01〜50g/Lの範囲であり、かつ6価クロムを含有しないアルミニウム又はアルミニウム合金用3価クロメート液を提供する。
また、本発明は、アルミニウム又はアルミニウム合金の表面を請求項1から3のいずれか1項に記載の3価クロメート液に接触させる工程を含む、アルミニウム又はアルミニウム合金の表面に耐食性皮膜を形成する方法を提供する。
本発明の3価クロメート液は、3価クロム、亜鉛、コバルト、ニッケル及びその組み合わせからなる群から選択される金属、並びにフッ素を含有する。
3価クロム源としては、塩化クロム、硫酸クロム、硝酸クロム、酢酸クロム等の3価クロム塩及びクロム酸や重クロム酸塩等の6価クロムを還元剤にて3価に還元した3価クロムからなる群から選択される1種あるいは2種以上を使用することができる。3価クロムの濃度は、水溶液中0.01〜100g/Lの範囲であるのが好ましく、0.05〜20g/Lの範囲であるのがより好ましい。3価クロムの濃度が上記範囲内であれば、連続的に安定な3価クロメート皮膜が形成でき、優れた耐食性が得られる。
亜鉛源としては、塩化亜鉛、硫酸亜鉛、硝酸亜鉛、酢酸亜鉛、水酸化亜鉛、酸化亜鉛、炭酸亜鉛等の亜鉛化合物が挙げられる。これらの亜鉛化合物は1種あるいは2種以上を混合して使用することができる。亜鉛の濃度は、水溶液中0.01〜100g/Lの範囲であるのが好ましく、0.05〜20g/Lの範囲であるのがより好ましい。
コバルト源としては、塩化コバルト、硫酸コバルト、硝酸コバルト、酢酸コバルト等のコバルト化合物が挙げられる。これらのコバルト化合物は1種あるいは2種以上を混合して使用することができる。コバルトの濃度は、水溶液中0.01〜100g/Lの範囲であるのが好ましく、0.1〜50g/Lの範囲であるのがより好ましい。
ニッケル源、塩化ニッケル、硫酸ニッケル、硝酸ニッケル、酢酸ニッケル等のニッケル化合物が挙げられる。これらのニッケル化合物は1種あるいは2種以上を混合して使用することができる。ニッケルの濃度は、水溶液中0.01〜100g/Lの範囲であるのが好ましく、0.1〜50g/Lの範囲であるのがより好ましい。
上記金属を2種以上混合して使用する場合、金属の合計濃度は水溶液中0.01〜100g/Lの範囲であるのが好ましく、0.1〜50g/Lの範囲であるのがより好ましい。
フッ素源としては、フッ化水素、フッ化ナトリウム、フッ化アンモニウム、フッ化カリウム、フッ化水素ナトリウム、フッ化水素アンモニウム、フッ化水素カリウム、珪フッ化物、ホウフッ化物等のフッ素化合物が挙げられる。これらのフッ素化合物は1種あるいは2種以上を混合して使用することができる。フッ素の濃度は、水溶液中0.01〜50g/Lの範囲であるのが好ましく、0.05〜10g/Lの範囲であるのがより好ましい。
本発明の3価クロメート液は、好ましくはpHが0.5〜6の範囲であり、より好ましくは1.0〜4.0の範囲である。なお、pHを調製するために、塩酸、硫酸、硝酸等の無機酸や水酸化アルカリ、アンモニア水などのアルカリ剤を用いることができる。
また、本発明の3価クロメート液は、リン化合物を含まなくても十分な耐食性を達成することができる。逆に、本発明の3価クロメート液中にリンが存在すると、沈殿を生じるために好ましくない。
本発明で用いる処理液における上記必須成分の残分は水である。
また、アルミニウム又はアルミニウム合金表面は、必要に応じて、3価クロメート皮膜形成の前処理として脱脂、エッチング、活性化等の従来の6価クロメート皮膜の形成の場合と同様の処理を行うこともできる。
さらに、耐食性の向上、外観の向上、着色等を目的として、3価クロメート皮膜形成後に塗装を含むオーバーコート等を施してもよい。
脱脂はディップソール社製AL−47を用いて行った(30mL/L:50℃で5分間浸漬)。
エッチングはディップソール社製#91を用いて行った(25g/L:50℃で30秒間浸漬)。
活性は62%硝酸(500mL/L)又はディップソール社製ALZ−740(150g/L)+62%硝酸(750mL/L)を用いて行った(室温で20秒間浸漬)。
乾燥は60℃で10分間行った。
耐食性評価方法は、JIS Z2371に準じ、35℃5%塩水噴霧試験を行い、240時間後の発錆面積を5段階で評価した。
密着性評価方法は、3価クロメート皮膜形成及び乾燥後、約24時間放置したものを溶剤系塗料に浸漬し、焼き付けを行い、さらに24時間放置後煮沸した純粋に時間浸漬し、取り出して約1時間放置した後、碁盤目試験、テープ剥離を行い、5段階で評価した。
