Advanced Physical Vapor Deposition for superior durability, performance and aesthetics
Premium PVD Coating Solutions for Industrial Applications
Physical Vapor Deposition (PVD) is an advanced thin-film coating technology that transforms component performance through microscopic ceramic layers. JLYPT specialises in precision PVD coatings that deliver exceptional hardness (up to 3500 HV), superior wear resistance, and enhanced thermal stability. Our coating solutions protect cutting tools, medical devices, automotive components, and decorative parts in the most demanding environments.
With expertise in Titanium Nitride (TiN), Chromium Nitride (CrN), Titanium Carbonitride (TiCN), Diamond-Like Carbon (DLC), Aluminium Titanium Nitride (AlTiN), and Zirconium Nitride (ZrN), we deliver tailored coating formulations that extend tool life, reduce friction, and improve part longevity. Our coating thickness ranges from 1 to 5 µm, precisely controlled to meet your application requirements.
Whether you require cutting tool enhancement for metalworking, biocompatible coatings for surgical instruments, corrosion-resistant finishes for aerospace applications, or decorative coatings for consumer products, JLYPT combines advanced PVD technology with expert material science to exceed your surface finishing specifications.
Titanium Nitride (TiN) Coating
Gold-standard PVD coating offering outstanding hardness (3200+ HV) and thermal stability up to 600°C. Ideal for cutting tools, milling inserts and drills where high temperatures and abrasive contact occur. Superior adhesion extends tool life by 300-500%.
Chromium Nitride (CrN) Coating
Engineered for exceptional corrosion resistance with hardness up to 2800 HV. Protects medical implants, surgical instruments and components exposed to harsh chemical environments. FDA and biocompatibility certification available.
TiCN, DLC, AlTiN & ZrN Specialised Coatings
Advanced multi-layer and specialty formulations: TiCN for balanced hardness and toughness, DLC for low-friction applications, AlTiN for extreme temperatures to 900°C, and ZrN for decorative finishes. Custom formulations available.

PVD Coating Advantages
Extreme Hardness & Durability
Hardness up to 3500 HV provides exceptional resistance to wear, abrasion and deformation. Components maintain dimensional accuracy under extreme stress, dramatically extending service life.
Superior Wear Resistance
Ceramic layers create a barrier against abrasive contact, reducing friction and material loss. Cutting tools experience 300-500% longer life, reducing costs and improving productivity.
Low Friction & Thermal Management
PVD reduces friction coefficients, lowering heat generation and enabling higher cutting speeds. DLC and AlTiN dissipate heat efficiently at temperatures exceeding 900°C.
Biocompatible & FDA-Approved Options
CrN and custom formulations are biocompatible for medical devices, implants and patient-contact instruments. ISO 10993 testing and FDA documentation provided.
Decorative Finishes & Aesthetic Appeal
Premium gold, bronze, black and silver finishes for consumer products, jewellery, watchmaking and architectural uses. Hypoallergenic and fade-resistant.
Temperature Resistance & Thermal Stability
TiN withstands 600°C, AlTiN up to 900°C. Coatings maintain hardness and adhesion under thermal cycling, vibration and thermal shock.
PVD Coating Process
Component Preparation & Cleaning
Parts are thoroughly cleaned, degreased and pre-treated to remove contaminants. Substrate surfaces are inspected and any imperfections corrected for optimal adhesion.
Substrate Conditioning & Ion Bombardment
Ion bombardment enhances surface activation and adhesion. Removes oxide layers and creates optimal surface conditions for PVD deposition.
Vapor Deposition & Layer Formation
Metallic and gas elements are ionised in a controlled vacuum chamber. Ions form hard ceramic layers at precise thickness (1-5 µm) with continuously monitored parameters.
Multi-Layer & Specialty Coating
For advanced applications, multiple coating layers with different formulations are deposited to achieve optimised hardness, toughness and performance.
Quality Control & Finishing
Coated parts undergo adhesion verification (scratch tests), hardness measurement, thickness verification, and visual inspection before secure packaging.

Frequently Asked Questions
What is the difference between PVD and CVD coating?
PVD uses physical processes at lower temperatures (200-400°C), ideal for temperature-sensitive substrates. CVD uses chemical reactions at higher temperatures (800-1200°C), offering greater thickness but risking substrate distortion. PVD is thinner (1-5 µm) with superior adhesion; CVD is thicker but may affect dimensions.
How long do PVD coatings last?
Cutting tools with TiN typically last 3-5× longer than uncoated. In harsh industrial environments coatings may last 6-12 months. Automotive and aerospace components maintain performance for 5-10 years. Medical implants with biocompatible coatings can last 15+ years.
What substrates are compatible with PVD coating?
Steels (tool, stainless, carbon), tungsten carbide, titanium alloys, aluminium, copper, and various specialty alloys. The low-temperature process (200-400°C) minimises substrate distortion. We conduct compatibility assessments for unusual substrates.
What batch sizes and lead times do you offer?
From single prototypes to 1000+ parts. Standard lead times: 2-3 weeks for batches under 100 parts, 3-4 weeks for larger quantities. Rush processing available for urgent requirements.
Can components be re-coated?
Yes. Stripping via controlled chemical or plasma processes removes existing coatings without damaging substrates, then full preparation and coating process is repeated. Typically viable 2-3 times per tool.
What quality testing do your PVD coatings undergo?
Hardness (Vickers), adhesion (scratch and bend tests), thickness (X-ray fluorescence), surface roughness and visual inspection. Medical coatings include ISO 10993 biocompatibility and FDA documentation. ISO 9001 certified.
