Evaporation Boat: Key Component in Thin Film Deposition

An evaporation boat, or crucible, is a crucial component in thermal vacuum deposition (TVD) systems. Its primary function is to contain and heat the material to be deposited, allowing it to evaporate and coat the substrate within the vacuum chamber.

What is Thin Film Deposition?

Thin film deposition is a technique used to apply a material layer onto a substrate surface with extremely thin thicknesses, typically in the nanometer to micrometer range. This technique is widely employed across various industries, such as:

  • Electronics: Manufacturing semiconductors, transistors, and other electronic components.
  • Optics: Producing optical lenses, filters, and mirrors.
  • Medical: Creating biomedical implants, prostheses, and other medical devices.
  • Aerospace: Developing anti-corrosion, anti-scratch, and heat-resistant coatings for aircraft and satellites.

How Does an Evaporation Boat Work?

Evaporation boats are typically made from heat-resistant and highly conductive materials such as graphite, molybdenum, tungsten, or boron nitride. The material to be deposited, in the form of small pieces or powder, is placed inside the evaporation boat.

The evaporation boat is then heated using various methods, such as resistive heating or electron beam heating. This heating causes the material inside the boat to evaporate, transforming it into vapor. The vapor then enters the vacuum chamber and moves towards the substrate, where it condenses and forms a thin film coating on the substrate’s surface.

Seberapa tahan Aluminium Alloy terhadap korosi?

by with No Comment Knowledge

Ketahanan korosi aluminium tercipta oleh inert oxide film yang terbentuk pada permukaan logam yang menyediakan lapisan pelindung, sehingga mencegah permukaan aluminium terpapar ke lingkungannya.

Oxide Film di permukaan terbentuk karena reaksi kimia antar permukaan aluminium dengan oksigen dan air. Faktanya, ini adalah tahap pertama dari korosi logam. Meskipun lapisan oksida hanya setipis 5-10 nm.

Aluminum corrosion chart by pH

Di sebagian besar lingkungan, laju korosi aluminium alloy menurun seiring waktu sebagian karena stabilitas lapisan oksida menentukan ketahanannya terhadap korosi, yang bergantung pada nilai pH lingkungan. Biasanya, oxide film stabil pada kisaran pH sekitar 4 hingga 8. Jika pH di bawah 4, asam akan larut, dan jika pH di atas 8, akan melarutkan alkali untuk membentuk padatan kristal, yaitu karat.

Dalam industri pengecoran, untuk memperbaiki sifat pengecoran aluminium dan mengurangi cacat pengecoran aluminium, pengecoran logam sering menambahkan kandungan Si yang lebih tinggi ke aluminium alloy, yang membuat korosi lokal lebih mungkin terjadi dan mencegah anodisasi untuk menurunkan ketahanan korosi dari aluminium casting.

Untuk mengoptimalkan ketahanan korosi pada cast aluminium alloy, perlu dipahami hubungan antara proses produksi aluminium alloy dan struktur mikro aluminium. Oleh karena itu, perlu dilakukan kajian komprehensif terhadap penelitian korosi logam aluminium alloy (secara umum) dan beberapa metode pengecoran aluminium, seperti sand casting, Low Pressure Die Casting dll.
