Description
セラミックスからなる容器内に収容されたクロム酸水溶液(比較例)を焼成することにより、焼成粉末を生成し、この焼成粉末2.5gの中に含まれるクロムの含有量及び6価クロムの含有量を測定して、6価クロムの濃度を算出した。また同様にセラミックスからなる容器内に収容されたリン酸クロム水溶液(実施例)を焼成することにより、焼成粉末を生成し、この焼成粉末2.5gの中に含まれるクロムの含有量及び6価クロムの含有量を測定して、6価クロムの濃度を算出した。焼成時間は3時間とした。焼成回数は1回とした。焼成温度を、比較例1では410℃、比較例2では460℃、比較例3では500℃、比較例4では600℃、比較例5では700℃、実施例1では410℃、実施例2では500℃、実施例3では600℃、実施例4では700℃とした。クロムの含有量及び6価クロムの含有量は、 ジフェニルカルバジド吸光光度法により測定した。測定機器には、日立製のU-2000ダ ブルビーム分光光度計を使用した。比較例1の焼成粉末は黒色であった。比較例2及び3の焼成粉末は暗緑色であった。比較例4及び5の焼成粉末は明緑色であった。実施例1〜4の焼成粉末はいずれも明緑色であった。6価クロムの濃度が1000ppm(0.1質量%)以下である場合には、6価クロムが少ないとして、「good」で評価した。6価クロムの濃度が1000ppm(0.1質量%)超である場合には、6価クロムが多いとして、「poor」で評価した。
所定のサンプルを準備し、MN値とFe付着量を測定することで、耐ビルドアップ性を評価した。図1はMN値を測定する測定機器の概略図である。同図に示すように、溶射試験片1及び溶射試験片1´を重ねこれらの間(つまり、溶射面Bと溶射面Cとの間)にビルドアップ原料2を介在させた。また、溶射試験片1の上面である溶射面Aにもビルドアップ原料2を散布し、その上から半月形ロール3を矢印X1方向に押しつけて荷重をかけながら矢印X2方向に往復運動を行うことで、溶射面A〜C各面のビルドアップ状況を評価した。
