Applications of PM5 Gen2 in Titanium Thickness Measurement

About Titanium

Titanium:Titanium is a silvery-white transition metal characterized by light weight, high strength, and good corrosion resistance. Due to its stable chemical properties, good resistance to high and low temperatures, strong acid and alkali, as well as high strength and low density, it is known as the "space metal". Using the components made of titanium can greatly ensure the safety and reliability of devices.

Key Advantages:

High Strength:Titanium metal has excellent strength and is suitable for applications requiring high-strength materials.

Corrosion Resistance:Titanium metal is resistant to chemical corrosion, extending the life of the material.

Low Density:Titanium is lightweight and is suitable for applications where weight reduction is required, such as in the aerospace field.

Bio-compatibility: Titanium metal has good compatibility with human tissue and is often used in medical devices and artificial joints.

Lightweight: Due to its low density and high strength, titanium metal helps to make products lighter and more efficient.

Durability: Titanium metal has excellent durability, extending product life and reducing maintenance costs.

‌Environmentally friendly and recyclable‌: Titanium metal can be recycled and reused, which is beneficial to resource recycling and environmental protection.

Wide Applications of Titanium

Chemical Industry:Because titanium has good corrosion resistance, it is often used to make industrial corrosion-resistant equipment.

Aerospace Industry:Titanium is often used to make aircraft parts because of its high strength and light weight.
Orthopedic Transplantation:Because of titanium's superior biocompatibility and high strength, titanium can be used as human orthopedic implants in the medical field.

Dental Implants:In addition to surgical implants, titanium can also be used as dental implants.

Measurement Analysis

However the safety of parts affects the overall safety of use. The key parts are complex and if they are not processed properly, the use of the entire product will be affected. We have received product samples from some aviation, aerospace and defense technology research and development companies, and the thickness is generally between 0.17-0.3mm and this sample is semicircular, which means the sample is very thin and has small area for probe to be well coupled with the workpiece.

According to the thickness range, we select the PM5 Gen2 High-precision Ultrasonic Thickness Gauge, it is a powerful and easy-to-operate non destructive testing equipment. PM5 Gen2 can realize most of difficult thickness measurement using single-element high-frequency narrow pulse probes. In this case, we used D15A probe and D20A probe to measure the thin titanium workpiece.

Measurement Results

The test results of using PM5 Gen2 standard probe 15M narrow pulse compound wafer probe are as follows:

Under the I-ME Measurement Modes, PM5 Gen2 captured many times of the bottom echoes of titanium workpiece.And this thickness testing equipment showed the great accuracy and high resolution, which can up to 0.001mm.

In order to measure smaller contact surfaces more stably, a 20M high-frequency probe and probe holder were selected. The following figure shows the test results using a 20M high-frequency small-diameter probe and holder.

About Probe Holder

It's a kind of ultrasonic accessories that developed independently by YUSHI. The purpose of probe holder is help to achieve well coupling and stable thickness measurement when the workpiece have irregular shapes.

Comparing the two probes, we can see that the measurement effect of the 20M small probe and holder is also very good, with high sensitivity and good resolution. It can clearly distinguish multiple bottom echoes, and the measurement results are accurate and reliable.
