Film, thin film coating on the vacuum introduction

Film, thin film coating on the vacuum introduction

Film: the film can be considered a two-dimensional material. In the strict academic sense, that only aggregate thickness is less than the thickness of the material characteristics of a real film, otherwise it is generally thin material. Characterized thickness: is the nature of the use of certain basic materials phenomenon will occur abnormal changes in the case of thin material thickness aggregation determined, i.e., when selected for a physical or mechanical properties different from the reference beginning to show it typically has a thickness characteristics when, is characterized in substance to the film thickness.

The main properties of the film：

Thickness: The more uniform the better, should generally be controlled within a range, such as 5, which is about the size of the workpiece coating system

Film surface morphology: transmission electron microscope by scanning electron microscopy (SEM) (TEM) analysis showed the like particle state, the availability of dense film surface, defect status, the annealing treatment on the membrane surface and other information.

Membrane organization features: X-ray diffraction analysis of the composition of the film, and other information available to the purity of the film. Film stress: the smaller the better films of internal stress, the internal pressure of the annealing process can maximize the release of the film.

Characteristics of the film and the substrate contact: mainly refers to the adhesion between the film and the substrate, of course, the stronger the better adhesion, the film appears to avoid missing the open and so on.

Dense membrane: mainly refers to film hardness and abrasion resistance, to avoid the open circuit external scratches caused.

Chemistry membrane, thermal stability: the requirements for the metal film layer of the metal film layer prepared resistivity as low as possible, close to the bulk resistivity.

Film analysis commonly used methods:

Scanning electron microscopy SEM analyzes 10nm resolution is generally more than surface information, sample preparation simple.

Transmission electron microscopy TEM analyzes structural information, resolution of less than 1 atom, sample preparation difficult.

XRD analysis of the structure is the information, but can not analyze micro-structure information for the film, XRD given direction, SEM choose a good area, TEM-depth analysis, which is a combination of boxing.

The future development of coating industry must be vacuum coating

The future development of coating industry must be vacuum coating

there are two main types of professional coating methods,one is chemical deposition (CVD), one is physical climate accumulation, also called vacuum deposition (PVD).
Chemical coating is rich in a membrane element of gaseous reaction agent or liquid reaction required for other gas introducing echo chamber, in the process of chemical reaction to generate film substrate appearance at...tack. In the process of chemical film, simple solution pollution, if the coating appearance more impurities, owe better plating.

Chemical coating demand response temperature is very high, usually to control at 1000 ℃ or more, but many matrix data cannot be influenced by the high temperature, timely and cemented carbide, although can endured high temperature, because of the high temperature in chemical coating manufacturing environment will also constitute a coarse grains,which cause the brittle phase, function deterioration. If on the carbide TiN plating, diffusion of carbon will attack response and solution decarburized layer, the layer patience is poor, low flexural strength, constitute a taking shorten tool use.
Vacuum coating machine dispose of chemical coating attack in a series of questions excellently. Vacuum coating is under the condition of vacuum, choose low voltage, high current arc discharge skills, using gas discharge ability, use other discharge is the transpiration and restore the transpiration of target material and gas ionization, all using the accelerating effect of electric field, the accumulation and reaction products made by transpiration material on the workpiece.
All coating materials are in a vacuum environment after plasma accumulation in the appearance of workpiece, the disposal of the chemical plating solution of pollution question, not toxic or pollutants, plating film hardness higher, good wear resistance and corrosion resistance, more safe. Disposal of vacuum coating technology can control the temperature below 150 ℃ ~ 500 ℃, suitable for a variety of substrate materials, preparation of colorful coating, plating system of carbide cutting tools can make its full progress 2 ~ 10 times.

Coating principle is what?

Coating principle is what?

At present there are three kinds of commonly used PVD: vacuum evaporation, sputtering deposition and ion plating. They work as follows: really empty plating film is in 1.33 x10 ^ 3 and 1.33 x10 ^ - 4 under the pressure of pa, with heat source heating material such as electron beam evaporation, evaporation of atoms or molecules directly on the workpiece surface sediments. Sputtering coating: it is not the evaporation technology of physical vapor deposition method. When plating, the studio into a vacuum, into argon as working gas, and maintain its pressure is 0.13 to 1.33 Pa. Ion plating: is it under the condition of vacuum, the use of gas discharge so that gas or evaporation material ionization of evaporation in the gas ion or material under the action of ion bombardment, evaporation, material or other reactant vapor deposition on the workpiece.
Vacuum coating is mainly refers to a kind of need to be done under high vacuum coating, including many types, including vacuum ion evaporation, magnetron sputtering, MBE molecular beam epitaxy, laser sputtering deposition and so on many kinds of PLD. The main idea is divided into evaporation and sputtering.
Need coating known as substrate, the plating material is become a target. Substrate with target in the vacuum chamber.
Evaporation coating is to heat the surface of target component to groups of atoms, or ions form by evaporation, and sedimentation in the substrate surface, through the film-forming process (scatter - island structure - the vagus structure - layered growth) form the membrane. For sputtering coating, can be simple to understand for the use of electronic or high-energy laser bombardment of target, and the surface components form groups of atoms, or ions was sputtering, and eventually deposited on the substrate surface, experience the film-forming process, eventually form a thin film.
