Description
a.混合:0.8ミクロンの平均粒径を有する144kgの炭化タングステン(WC)、約1ミクロンの平均粒径を有する30kgの鉄(Fe)粉末、1〜2ミクロンの平均粒径を有する15kgの炭化クロム(Cr3C2)粉末、6kgのケイ素(Si)粉末および4kgのパラフィンワックスを、粉砕媒体としてアルコール、および、800kgの合計質量を有する複数のセメント炭化タングステンボールを用いたアトリタ製粉機(attritor mill)で粉末を一緒に3時間粉砕することで混合し、前駆材料スラリーを得た。スラリーを乾燥させて混合粉末を得、および凝集体を粉砕してゆるい粉末を得た。
b.第1の顆粒化:粉末を結合材料と一緒に回転ドラム内で回転させることで顆粒化し、ふるいにかけて、約75〜約225ミクロンの平均サイズを有する複数の顆粒を得、複数の「未完成の」顆粒(すなわち、結合材料によってまとまっている粉末粒子を含んでなる顆粒)を得た。
c.予備加熱処理:未完成の顆粒を黒鉛の箱に配置し、1020℃の温度まで加熱した。この温度は、材料の液体相焼結が実質的に一切起こらないよう十分低く、かつ、実質的に全ての結合材料が取り除かれるよう十分高く、粉末の固体相焼結が取り扱いに十分な強度を顆粒に提供するのに十分な温度であった。
d.第2の顆粒化:加熱処理のあと、顆粒をふるいにかけて約75〜225ミクロンの直径を有する複数の顆粒を選択した。
e.焼結加熱処理:選択した顆粒を次いで黒鉛の箱の中に置き、真空下の1160℃で、45分焼結し、顆粒の実質的な液体相焼結を可能にし、焼結顆粒を得た。焼結プロセスの間、一定の量の炭化クロム(Cr3C2)が分解するであろう一方で、比較的少量のWCのみが結合材料に溶解し得る。特定の仮説に限定することは望まないが、可能性として、実質的に全ての炭化クロム(Cr3C2)が液体結合材料に溶解し得、鉄族金属(FeまたはCoといった)、CrおよびCを含んでなる混合炭化化合物材料の結晶化が、材料の固化の際に起こり得る。溶解したWCの量は、およそ5〜8質量%であり、最大およそ1.5〜2.5原子%に対応し、これは、結合材料の溶融温度に実質的に影響を及ぼさないであろう。顆粒が実際よりも実質的に多くの鉄を含有した場合、顆粒の実質的な溶融は高くなり、焼結加熱処理の終わりには、鉄ベース材料の硬くて大きい集合体がもたらされ、集合体を粉砕して第1の複数の顆粒を得るのは大変困難であっただろう。しかし、顆粒に存在する鉄が少なすぎる場合、材料の十分な液体相焼結が起こらず、顆粒は十分な強度を欠けていただろう。例えば、複数の鉄に富んだ顆粒をさらに導入する必要性を避けて、溶射プロセスに関して、たった一組の複数の顆粒を提供および使用しようとした場合、顆粒は、この実施例で使用される15質量%の代わりに、約69質量%の鉄を含んでなる必要があり、顆粒化が実行不可能なほど困難になり得る鉄ベースの硬い本体になっていただろう。
f.第3の顆粒化:焼結顆粒をアルゴン(Ar)雰囲気の50barの圧力下で熱間静水圧加圧(HIP)し、圧縮された本体を得た。圧縮された本体を次いで粉砕し、約60〜180ミクロンのサイズを有する顆粒を、ふるいにかけて選択し、第1の複数の顆粒を得た。
