What is the Different of PVD Coating Machine

PVD vacuum coating craft including evaporation plating, sputtering plating, ion plating and through these three different crafts, different coating machines are built.But how to choose the suitable pvd coating machine becoming a problem when purchaser find so many different machines on the website.This blog will introduce the different of vacuum technology machine for you to choose the suitable machine.  

PVD Coating Machine Characteristics

Evaporation coating machine

Advantages:

The purity of the coating is higher, in the pvd coating process of impurities are not easy to evaporate with the coating material.

Evaporation pvd coating process is simple and equipment cost is low, for some small batch, simple coating needs have certain advantages.

Operating cost of evaporation coating machine mainly lies in the heating energy consumption and the loss of coating materials, and the energy consumption is relatively low.

Cons:

The adhesion between the coating and the substrate is relatively weak, because the evaporation atoms have less kinetic energy when they reach the substrate and are not tightly bound to the substrate atoms.

When the pvd coating is subjected to greater external force or friction, the evaporation coating may fall off.

Sputtering coating machine

Advantages:

Sputtering coating has a high density, the sputtered atoms have a high kinetic energy, and can form a tighter packing structure when deposited.

Coating performs well in hardness and wear resistance, which is suitable for tool coating and protective coating of electronic components.

Cons:

In the sputtering coating process, the low sputtering rate of target atoms leads to low coating efficiency.

Equipment relatively complex and operation cost is higher, which requires a vacuum system, ion source, such as equipment and higher requirements for gas purity.

Ion coating machine

Advantages:

The adhesion between the coating and the substrate is strong, and the bombardment effect of ions on the substrate in the ion plating coating process makes the coating and the substrate form a strong chemical bond.l

Ion plating can prepare better structure and performance of the film, such as in the preparation of super-hard film (such as titanium nitride, etc.), ion plating can obtain better crystal structure and performance.l

The speed is relatively high, suitable for mass production.

Cons:

This coating equipment is more complex, the technical requirements are high, and the initial investment cost is large.

Different Pvd Coating Applicable Materials

Evaporation coating machine

Suitable for low evaporation temperature, high vapor pressure materials, such as aluminum, silver, gold and other metal materials. For some organic materials, evaporation can also be used for coating under specific conditions.

Sputtering coating machine

Most materials can be sputtered, including metals, alloys, ceramics, semiconductors, etc. Especially for some materials with high melting point and difficult to evaporate, sputtering has obvious advantages. For example, when preparing ceramic coating such as silicon nitride, sputtering is a common method.

Ion plating coating machine

It can be used for ion coating a variety of materials, including metals, alloys, compounds, etc. In the preparation of coating with special performance requirements, such as coating with high hardness and good electrical conductivity, ion plating can be achieved by precisely controlling the process parameters. For example, in the manufacture of some high-end electronic devices, ion plating is used to deposit multilayer composite films.

PVD Coating Machine Cost

PVD coating machine acquisition cost

The equipment procurement cost of evaporation coating machine is relatively low, suitable for factories with limited budgets.

Sputtering coating machine equipment is relatively complex, high procurement cost.

Ion plating machine due to complex technology, high requirements for equipment performance, the highest procurement cost.

Factories need to make choices in procurement according to their financial situation and long-term investment planning.

PVD coating machine running cost

Evaporation coating machine mainly lies in the heating energy consumption and the loss of coating materials. Generally speaking, its energy consumption is relatively low, but if methods such as electron beam heating are used, the maintenance requirements for the equipment are high, which may increase the maintenance cost.

Sputtering coating machine is high, in addition to high energy consumption and high gas purity requirements, it also needs to continue to consume high-quality inert gases (such as argon), and the loss of the target is also large, and the replacement cost of the target is high.

Ion plating machine is also high, in addition to energy consumption and gas consumption, but also need to regularly maintain key components such as ion sources, maintenance costs are relatively high. Although the unit time output is higher, the overall energy and material consumption is also larger, and cost effectiveness needs to be considered

In short, suitable coating products for different application scenarios. If you want to know more information about the coating machine equipment, welcome to leave a message in the background.
