Description
溶射皮膜を形成するための基材として、縦50mm、横50mm、厚さ5mmの鋼鉄(SUS304)製の平板を用意し、平均粒子径(D50)が3μmの溶射粉末が分散媒中で分散してなる懸濁液を溶射材料として、大気中でサスペンション高速フレーム溶射を行って各試験片を作製した。溶射粉末としては、窒化アルミニウム(実施例1)、窒化クロム(実施例2)、炭化クロム(実施例3)、窒化チタン(実施例4)、炭化チタン(実施例5)、及びホウ化チタン(実施例6)を使用した。溶射ガンのノズルとしては、図2で示した構造のものを使用した。分散媒は、実施例3、5、6では水を用い、実施例1、2、4ではエタノールを用いた。
実施例1~6及び比較例1において成膜した皮膜の断面組織の観察を行った。また、ビッカース硬さ試験機により、各皮膜の表面硬さHVを測定した。図4は、実施例1~6及び比較例1において成膜した各皮膜の走査型電子顕微鏡(SEM)による断面観察写真と、それぞれの断面硬さHV及び膜厚の大きさの数値をまとめた表である。実施例1~6のサスペンション高速フレーム溶射法によって成膜した溶射皮膜の断面は、比較例1のスラリーの塗布・焼成によって成膜した皮膜の断面よりも緻密であり、また、実施例1~6において成膜した溶射皮膜の表面硬さは、比較例1において成膜した皮膜の表面硬さよりもはるかに高い値となった。
実施例1~6において成膜した皮膜の成分分析を行った。図5は、実施例1~6において作製した各皮膜の走査型電子顕微鏡(SEM)による断面観察写真と、その範囲内における各成分の分布を示すマッピング写真、及び当該範囲内における酸素含有量である。成分分析及びマッピングは、エネルギー分散型X線分析装置(EDX)を用いて行った。
実施例2、3において成膜した溶射皮膜と、比較例1において成膜した皮膜のそれぞれの耐摩耗性を評価した。また、この試験では、比較例2、3として、それぞれ大気圧プラズマ溶射法によって溶射皮膜を成膜した試験片も使用した。比較例2において溶射材料は、粒度が10~45μmの酸化アルミニウムの粉末を使用し、比較例3において溶射材料は、粒度が10~45μmの酸化クロムの粉末を使用した。
実施例1、2、6において成膜した溶射皮膜と、比較例1において成膜した皮膜と、比較例4である鋼鉄(SUS304)製の基材のそれぞれの溶融金属(亜鉛)に対する濡れ性を評価した。図7は、実施例1、2、6及び比較例1において作製した試験片、並びに比較例4の試験片のそれぞれの表面における溶融亜鉛に対する接触角を測定する様子を表す写真図である。
追加の試験片として、下地に炭化タングステン-コバルトサーメット溶射皮膜を形成したうえで、それぞれ実施例1、2、6と同じ条件で、窒化アルミニウム(実施例7)、窒化クロム(実施例8)、及び硼化チタン(実施例9)の各材料を用いたサスペンション高速フレーム溶射法による溶射皮膜を備える試験片、及び下地に炭化タングステン-コバルトサーメット溶射皮膜を形成したうえで、比較例1と同じ条件で皮膜形成を行った試験片(比較例5)を作製した。下層である炭化タングステン-コバルトサーメット溶射皮膜は、粒度が10~53μmの炭化タングステン-コバルトサーメット粉末材料を溶射材料として用い、高速フレーム溶射により成膜した。浴成分との反応性は、各試験片を溶融亜鉛ポットに168時間浸漬した後の断面観察と、上層皮膜の成分分析で評価した。
