Nanoindentation Testing Service
CD BioSustainable provides precise nanoindentation testing for eco-friendly materials. We analyze micro-mechanical properties, including hardness, elastic modulus, creep, and interface bonding strength, helping customers understand mechanical characteristics and structure-performance relationships, and supporting green material design optimization and application reliability.
What is Nanoindentation Testing?
Nanoindentation measures material deformation under applied force using a diamond indenter. Load and displacement are recorded as the indenter penetrates the sample. Based on the Oliver-Pharr method, it calculates hardness and elastic modulus, revealing key mechanical properties for durability and performance.
Why Do Nanoindentation Testing?
- Non-destructive Analysis
Nanoindentation offers a non-destructive approach to material analysis, enabling the study of material properties without compromising the integrity of the sample.
- Material Property Mapping
By conducting multiple indents across a sample, a detailed map of material properties can be generated, providing a comprehensive view of property variations within the material.
- Nanoscale Measurement Precision
The technique allows for precise measurements at the nanoscale, which is essential for understanding the mechanical properties of materials in modern technologies where dimensions are shrinking.
- Environmental Control
Nanoindentation can be performed under various environmental conditions, including different temperatures and controlled atmospheres, which is vital for studying material behavior in specific applications.

Methods of Nanoindentation Testing
The nanoindentation process typically involves several methodologies, including:
- Static Indentation: A constant load is applied to measure the hardness and elastic modulus under quasi-static conditions.
- Dynamic Indentation: Small oscillatory loads are superimposed on the primary loading to evaluate the continuous mechanical response of the material, providing insights into its viscoelastic properties.
- Continuous Stiffness Measurement: This technique allows for the determination of local mechanical properties as the indentation progresses, crucial for materials with graded structures.
Sample Requirements
For effective nanoindentation testing, specific sample requirements must be met:
- Surface Preparation: Samples must have a polished and clean surface to ensure accurate measurements.
- Material Thickness: For thin films or coatings, the thickness must be considered, as it can affect the measurement of mechanical properties.
Sample types suitable for nanoindentation testing include:
Polymers
Biodegradable plastics and other sustainable polymer composites.
Metals
Environmentally friendly alloys and coatings.
Ceramics
