Description
デバイスは、１００Ｗ／ｍＫ超過の導電性を有する材料で作られ溶融先端を備え冷却された不融性ソノトロードに、導波管によって接続された圧電変換器と、入力材料送達システムと、材料溶融システムと、処理チャンバ、高電圧発生器と、真空ポンプとを備える。圧電変換器は、材料噴霧に使用される機械的エネルギー源であり、２０ｋＨｚ超過の作業周波数を有し、高電圧発生器によって電力供給される。圧電変換器は、デバイス・フレームへの取付け具として作用し変換器の振動振幅を増加させる、ねじ締結具を通して導波管に接続される。導波管は、ねじ締結具を通して不融性ソノトロードに接続される。不融性ソノトロードは、流動する冷却媒体によって処理チャンバの内部で冷却され、同時に、溶融先端のためのラジエータとして作用する。ソノトロードの二重の役割（振動の伝達と熱の除去）により、熱伝導率が高く、即ち１００Ｗ／ｍＫ超であり、１００ ＨＶ５超の硬度を有する材料を使用する必要がある。冷却媒体の漏れおよび処理チャンバ内への浸入を防ぐシールは、ゼロ振幅振動ノードに、即ち導波管およびソノトロードの長さの半分のところに配置される。冷却媒体は、空気またはジエチレングリコールである。溶融先端は、ねじ締結具によってソノトロードに接続されるか、または拡散接合によって固定される。溶融システムは熱エネルギーを溶融先端に送達する。入力材料に応じて、溶融システムは、不融性タングステン電極およびアーク放電出力源もしくはプラズマ・トーチ、アーク放電出力源およびプラズマ・ガス吹込みシステム、またはレンズおよびレーザー出力源から成ってもよい。同時に、デバイスは、入力材料を溶融先端に送達するシステムを備える。入力材料の形態に応じて、システムは、当該分野で知られているワイヤ・フィーダおよび処理チャンバにつながるチャネル、不規則な顆粒または粉末の形態の材料の振動フィーダ、ロッドの形態の入力材料を溶融先端に導入する機械的プッシャの形で実現することができる。処理チャンバは、当該分野で知られているように冷却され、保護ガスおよび入力材料チャネル、ならびに真空ポンプとの接続部の役割を果たすチャネルを備える。 The device consists of a piezoelectric transducer connected by a waveguide to a cooled infusible sonotrode made of a material with a conductivity greater than 100 W/mK and equipped with a melting tip, an input material delivery system, and a material melting system. , a process chamber, a high voltage generator, and a vacuum pump. A piezoelectric transducer is a mechanical energy source used for material atomization, has a working frequency of over 20 kHz and is powered by a high voltage generator. The piezoelectric transducer is connected to the waveguide through screw fasteners that act as attachments to the device frame and increase the vibration amplitude of the transducer. The waveguide is connected to the infusible sonotrode through a threaded fastener. The infusible sonotrode is cooled inside the processing chamber by a flowing cooling medium and at the same time acts as a radiator for the melting tip. The dual role of the sonotrode (vibration transmission and heat removal) requires the use of materials with high thermal conductivity, ie >100 W/mK, and hardness > 100 HV5. A seal that prevents leakage of the cooling medium and entry into the process chamber is placed at the zero amplitude vibration node, ie half the length of the waveguide and sonotrode. The cooling medium is air or diethylene glycol. The fusion tip is connected to the sonotrode by a threaded fastener or fixed by diffusion bonding. A melting system delivers thermal energy to the melting tip. Depending on the input material, the melting system may consist of an infusible tungsten electrode and arc discharge power source or plasma torch, an arc discharge power source and plasma gas blowing system, or a lens and laser power source. At the same time, the device includes a system for delivering input material to the melting tip. Depending on the form of the input material, the system will melt the input material in the form of rods, vibrating feeders for materials in the form of irregular granules or powders, channels leading to wire feeders and processing chambers known in the art. It can be realized in the form of a mechanical pusher introduced at the tip. The processing chamber is cooled as is known in the art and comprises protective gas and input material channels, as well as channels that serve as connections to vacuum pumps.
