Abstract
Description
1. 被膜のダイヤモンドに対する強い接着結合。
2. 被覆方法は、ダイヤモンド砂粒の粒子表面の大部分、または、多結晶ダイヤモンド製部品全表面の、連続的被覆を達成しなければならない。
3. 溶融金属のダイヤモンドへの拡散を防ぐのに十分な厚さと適合する構造。
4. 被膜は、実質的に多孔性および微小亀裂を有してはならない。それは、多孔性と微小亀裂があると、酸素または溶融金属がダイヤモンドを攻撃できるからである。
5. 被膜は、応力を減少させるために、ダイヤモンドあるいはダイヤモンド含有材料の熱膨張係数(CTE)に近いCTEを有さなければならない。
6. 機械的磨耗に抵抗するのに十分な硬度、しかし同時に、機械的あるいは熱的衝撃を受けている時に、被膜の脆性破壊ならびに微小亀裂を防ぐのに高められた靭性と延性。
7. 被膜の外部表面は、溶融金属バインダー、ろう付け、および鋳造合金による、良好なぬれ性を有しなければならない。
従来技術の被膜の中には、これらの上記の必要条件のすべてを満たすものは1つもない。
最上列: タングステンW
第2列: ダイヤモンドC
第3列: 炭化タングステンW2C
第4列: 炭化ケイ素SiC
第2被膜層は比較的に厚いから、ダイヤモンドあるいはSiC基材の線も第1被膜層からの炭化タングステンの線も見えない。
タングステンW
ダイヤモンドC
炭化タングステンW2C
炭化ケイ素SiC
炭化タングステンWC
ケイ素Si
黒鉛C
第1被膜層は比較的に薄いから、スペクトルは、基材(ダイヤモンド、SiC、Si)および被膜(タングステン、炭化タングステンWCおよびW2C)の両方に対する特性線を有している。
