PVD Coating
PVD hard coatings are extremely thin (a few micrometers) protective films that can improve the following surface properties of the substrate materials:
Hardness
Oxidization resistance
Coefficient of friction
Toughness
Chemical stability
Other more application scenarios
Applying a few microns of coating on cutting tools can increase cutting speed, significantly improve production efficiency, and extend the service life of the substrate material.
Coating Features
The coatings have good adhesion, high densification, little microparticals, with various architecture of gradient/multilayers/superlattice/nanocomposites
Coating Thickness：Can be thin or thick, with constant smoothness（as thin as 0.5μ，thick up to30μ）
Excellent adhesion between film and substrate
DLC coating
DLC (Diamond-like Carbon) is a metastable diamond-like amorphous carbon coating, containing a large amount of sp2 and sp3 bonds. The high sp3 bond content can bring high coating hardness, high stability, high oxidation resistance, low residual stress and low thermal conductivity.
Properties and application:
Smooth coating surface
Chemical inertness
High mechanical hardness and good wear resistance
Low friction coefficient between tool and workpiece, reducing friction
Good corrosion resistance
Suitable for biocompatible products

PECVD Coating Technology
Plasma Enhanced Chemical Vapor Deposition (PECVD) is a process that deposits extremely smooth, adherent amorphous diamond hard alloy coatings in a highly vacuum environment. Compared to PVD processes, PECVD processes use deep plating power supplies, do not require cathode targets, and the workpiece does not need to rotate in the furnace chamber. This process is a clean, pollution-free, reliable, and multifunctional coating process.
● Simple hardware, no additional ionization source required
● Composite magnetic field design, increasing ionization rate
● High deposition speed＞1μm/h
● Low deposition temperature ＜250℃
● Smooth surface, no large microparticle contamination
● Plasma cleaning products, maintenance-free
Simulation of non-equilibrium closed magnetic field

PECVD（for a-C:H）
Based on the requirements for wear resistance, lubrication, corrosion resistance, and high bonding strength of parts, the DLC coating is structurally designed based on the concept of multi-layer structure, gradient transition, and interface composite.

Notice BEFORE Coating
Huasheng coating process needs high temperature and high vacuun enviornment, so does tools be coated. Please check followed annoucement to fulfill our PVD coating performance:
✔ Workpiece able to be coated
To provide perfect process for tools Huasheng needs some basic information about coating tools like substrate material, hardness and temper temperature. Here are materials can be coated:
1. Alloy steel, HSS and stainless steel
2. Cement carbide
3. Titanium alloy
4. Nickle alloy
For chisel steel it has to be tempered twice or more over 500 degree centigrade and keep its hardness and electrical conductivity. Because whole tools would be coated inside chamber in PVD process so make sure the whole tool can meet these requirements.
✔ Coating area
Please note coating area of a tool with an area for clamping, it is not likely to full coating cover a whole tool. If there is somewhere should not be coated, please annoce us in advance.
✔ Largest coating size
Huasheng coating has a largest area of no more than φ900*1000mm
✔ Limits on tool surface
1. Tools for coating cannot be: electroplated, nitriding, carburized, parkerising, oxidized, TD, CVD or other surface treatment
2. There should not be rust, corrosion, oil paint, glue on tool surface
3. Surface roughness: with reach requirement of using, workpiece surface should be as much as smooth, surface Ra<0.2μm is better; for special mirror plastic mold, etched die it depends on product standard
4. Assembling die or mosaic tool must be disassembled
5. Welding ool surface should be completely clean without oxidation layer or hole on top
✔ What customer should provide
1. Materials and code of coating tools
2. Tempered teamperature and hardness
3. Note us surface needed coating
4. Dimensional accuracy smaller than 5μm tools need dimensional accuracy requirement
5. Cutting data and workpiece for us to provide perfecr coating
✔ Package and shipping
1. HSS and tool steel parts should be oiled before transferred
2. Tool should be packed individualy
3. After coating HSS and tool steel we will also oiled surface (except special requirement)
✔ Dimensional accuracy
1. Husheng PVD coating range from 0.5μm to 30μm, with precisely controlled of process
2. If you have high requirement of dimensional accuracy of product please leave the space and announce us in advande
✔ PVD coating limit
PVD coating can cover complex surface, but only can coat hole with pit-depth ratio no smaller than 1:1 and with coating thickness is thinner with depth.
✔ Recoating
Huasheng provides decoating service for customer (except some carbide tools)
