Overview服务概述

Diamond-like carbon, engineered for wear

为耐磨而设计的类金刚石涂层

Diamond-Like Carbon (DLC) coatings are advanced wear-resistant thin films designed for components operating under high loads, extreme friction and severe wear. Their exceptional hardness and low coefficient of friction reduce pitting, galling, seizure and premature failure, significantly extending component life.

类金刚石（DLC）涂层是面向高载荷、极端摩擦与严苛磨损工况设计的先进耐磨薄膜。凭借卓越的硬度与低摩擦系数，可减少点蚀、咬合、卡死与过早失效，显著延长部件寿命。

DLC is a family of carbon-based coatings — not a single coating type. Its properties can be tailored by adjusting hydrogen content, doping elements, coating structure and deposition process to meet specific application requirements.

DLC 是一个碳基涂层家族，而非单一涂层类型。可通过调整含氢量、掺杂元素、涂层结构与沉积工艺来定制性能，满足具体应用需求。

✓ Typical thickness 1–5 μm, hardness from 8 to over 80 GPa
✓ 典型厚度 1–5 μm，硬度 8 – 80+ GPa
✓ Excellent wear resistance and low friction
✓ 优异的耐磨性与低摩擦
✓ Improved corrosion resistance
✓ 更好的耐腐蚀性
✓ Longer component service life
✓ 更长的部件使用寿命

From a-C to DLC: the right film for the job

从 a-C 到 DLC：为工况选择合适的薄膜

◆

a-C Films

a-C 薄膜

Hydrogen-free films with a 3D network of sp³ and sp² bonded carbon, deposited by PVD methods such as vacuum cathodic arc and pulsed laser deposition.

无氢薄膜，由 sp³ 与 sp² 键合碳构成的 3D 网络，通过真空阴极弧、脉冲激光沉积等 PVD 方法制备。

◈

ta-C (Tetrahedral Amorphous Carbon)

ta-C（四面体非晶碳）

Amorphous diamond film fabricated by Filtered Arc (FA) with diamond-phase content up to 88% — ultra-high hardness, excellent adhesion and low friction.

通过过滤电弧（FA）制备的非晶金刚石薄膜，金刚石相含量可达 88%——超高硬度、优异附着力与低摩擦系数。

◍

a-C:H Films

a-C:H 薄膜

Hydrogen-containing DLC deposited by CVD with acetylene — generally softer than ta-C, tailored for less demanding conditions.

通过 CVD 引入乙炔制备的含氢 DLC，通常比 ta-C 软，适用于要求相对温和的工况。
