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.

6 Types of Spray Guns: Benefits and Drawbacks

Currently, there are many types of spray guns available in the market. Each type serves specific functions depending on the application. Based on painting methods, there are six types of spray guns commonly used today. What are these six types of spray guns, and what are their advantages and disadvantages?

1. Conventional Spray Gun

Invented over a century ago, the Conventional Spray Gun, also known as the Air Spray Gun, is still in use today, especially in the automotive field. Generally, Conventional Spray Guns are relatively inexpensive compared to other types.


  • High flexibility
  • Smooth finish


  • High overspray levels
  • Atomization at 0.2 to 0.3 MPa (30-40 psi) high air pressure, with a transfer efficiency of only 30% to 40%. This means that around 60% of your paint is wasted using this conventional spray gun.
  • High VOC waste production, causing significant pollution and health risks.

2. HVLP Spray Gun

High Volume, Low Pressure (HVLP) spray guns are designed to prevent overspray that occurs with conventional spray guns. HVLP uses lower air pressure, about 0.05 to 0.1 MPa (7-14 psi), while using more air to compensate for low pressure and good atomization.

HVLP spray guns are suitable for varnish, metallic painting, and enamel. They are frequently used for furniture, car repair, and personal projects.


  • Paint efficiency between 60-80%
  • Versatile applications: varnish, metallic painting, enamel for furniture, cars, and personal projects
  • Low VOC waste


  • Only suitable for low viscosity liquids
  • Can damage the tool if used with high viscosity liquids
  • Low paint transfer speed


3. LVLP Spray Gun 

Low Volume Low Pressure (LVLP) spray guns are an evolution of HVLP spray guns. HVLP requires a large air compressor, while LVLP can operate with a smaller one.

LVLP spray guns are ideal for beginners, can use waterborne paint, and have efficiency comparable to HVLP. However, LVLP has a narrower spray coverage and works better with low viscosity liquids, making it best for detailing or small objects.

4. Airless Spray Gun, Hydraulic-pressured-based

Airless Spray Guns use hydraulic pressure instead of air to atomize the coating or paint, with very high pressure ranging from 10 to 20 MPa (1,500-3,000 psi).

Airless spray guns are suitable for high viscosity coatings and large surfaces like walls, fences, bridges, and ships. Although they offer efficiency similar to HVLP, the finish is coarser, making them less suitable for small, detailed work.


  • Can handle high viscosity
  • Suitable for large surfaces
  • Efficiency of 60-80%


  • Coarse finish
  • Not suitable for detailed work

5. Electrostatic Spray Gun 

Electrostatic Spray Guns provide the highest transfer efficiency, with high current passing through the gun tip, charging the fluid particles negatively, which then get attracted to the positively charged surface.

Electrostatic spray guns are ideal for automotive primers, base coats, and top coats. However, the high efficiency comes with a high cost and certain limitations, such as the inability to coat plastics without special additives due to the Faraday Cage Effect.


  • Very smooth finish
  • High transfer efficiency (80-90%)


  • Cannot be used on plastics without special additives
  • High setup and maintenance costs

6. Krigsmann Kroma

aluminium alloy grade

Seberapa tahan Aluminium Alloy terhadap korosi?

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.
