Abstract
Description
− 粉末上への堆積の均一性、
− 粉末の粒の形状及び寸法の均一性、
− 方法の温度
− ガス放出の危険性
− (絶縁された)移動する分割された固体の静電特性、
− 機材の素材の仕上げと性質。粉末が機材に付着することを防ぐために、堆積の性質と顆粒のバインダーの性質との間のペアリングを正しく選択することが特に必要である。
− 追加成分または化合物の完全に制御され非常に少量な添加を得ることを可能にし、そのため追加化合物の微量の実施を可能にする。
− セラミック粉末の表面にまたはバインダー添加セラミック粉末の表面に追加化合物の均一な分布を得ることを可能にし、これは最終的にはセラミック構成部品が均一な性質を有することを意味する。
− 多数の追加化合物の添加を可能にし、これにより現存の解決策と比較して追加可能な化合物の数を増加させ、特定の性質をセラミック構成部品に与える可能性を増加させる。
− 追加化合物の信頼できる、再現可能で、混じりけのない堆積を可能にする。
− 着色顔料、またはより一般的には少なくとも1つの添加または追加化合物を含むバインダー添加セラミック粉末であって、当該バインダー添加セラミック粉末を用いてセラミック構成部品を製造する場合に、第1色の、より一般的には第1性質が与えられる、セラミック構成部品を得ることを可能にできる、バインダー添加セラミック粉末を得る、
− 当該バインダー添加セラミック粉末上に、少なくとも1つの追加着色または他の成分または化合物を、物理的蒸着(PVD)または化学蒸着(CVD)または電子層蒸着(ALD)により堆積するE3、
− その色が第1色とは異なる第2色である、またはより一般的には第1性質とは異なる第2性質が与えられる、セラミック構成部品を得るために、堆積された追加化合物を含むバインダー添加セラミック粉末を用いて、セラミック構成部品の製造を完成する。
