Vacuum coating is an important aspect of vacuum application field, it is based on vacuum technology, using physical or chemical methods, and the absorption of electron beam, molecular beam, ion beam, ion beam, radio frequency and magnetic control and a series of new technologies, for scientific research and practical production to provide a new film preparation process. Simply put, the method of vaporizing or sputtering a metal, alloy or compound in a vacuum so that it solidifies and deposits on the coated object (called a substrate, a substrate or a matrix) is called vacuum coating.
Advantages:
(1) Wide selection of film and matrix materials, film thickness can
be controlled to prepare a variety of functional films with
different functions.
(2) The film is prepared under vacuum conditions, the environment
is clean, the film is not easy to be polluted, so the film with
good density, high purity and uniform coating can be obtained.
(3) The bonding strength of the film and the matrix is good, and
the film is firm.
(4) Dry coating does not produce waste liquid, and no environmental
pollution.
Vacuum coating technology mainly includes vacuum evaporation
plating, vacuum sputtering plating, vacuum ion plating, vacuum beam
deposition, chemical vapor deposition and other methods. Except for
CVD, the other methods have the following characteristics in
common:
(1) all kinds of coating technology need a specific vacuum
environment, in order to ensure that the film material in the
process of heating evaporation or sputtering steam molecules formed
by the movement, not by a large number of gas molecules in the
atmosphere of the collision, block and interference, and eliminate
the adverse effects of impurities in the atmosphere.
(2) A variety of coating technologies need to have an evaporation
source or target, in order to evaporate the film material into a
gas. Due to the continuous improvement of source or target, greatly
expanded the selection of membrane materials, whether metal, metal
alloy, intermetallic compound, ceramic or organic material, can be
evaporated a variety of metal film and dielectric film, but also
can be evaporated at the same time different materials to get
multilayer film.
(3) evaporation or sputtering out of the film material, in the
process of film generation with the workpiece to be plated, the
film thickness can be more accurate measurement and control, so as
to ensure the uniformity of the film thickness.
(4) Each film can be accurately controlled through the fine-tuning
valve of the composition and mass fraction of the residual gas in
the coating chamber, so as to prevent the oxidation of the
evaporating material, reduce the mass fraction of oxygen to the
minimum extent, but also can be filled with inert gas, which is not
possible for wet coating.
(5) Due to the continuous improvement of coating equipment, the
coating process can be continuous, thus greatly improving the
output of products, and in the production process of environmental
pollution.
(6) Due to the vacuum condition of the film, so the film of high
purity, good compactness, bright surface does not need to be
processed, which makes the mechanical and chemical properties of
the film is better than electroplating film and chemical film.
