Observation of metallic tissue through chemical treatment.

You can gain clues about the quality of the product and issues through the organizational shape!

We will introduce the observation of metal structures through chemical treatment. By performing chemical treatment on metal samples, it is possible to clearly observe the metal structure. Observing the structure can confirm the condition of the sample and the history of applied heat and stress, providing clues about the quality of the product and any defects based on the structural shape. In the published catalog, you can find details on the observation of metal structures, such as the macrostructure of aluminum plates and the soldered parts of copper terminals. Additionally, we offer other services such as cross-sectional observation and various analysis services. Please feel free to contact us if you have any requests. [Published Content] - Macrostructure of aluminum plates - Soldered parts of copper terminals - Brass screws - Welded parts of SUS rods *For more details, please download the PDF or feel free to contact us.

Introducing examples of aluminum welding observations. Internal observations through X-ray fluoroscopy and CT scans provide clearer insights after cross-section preparation!

Here is a case study of the observation of aluminum spot welds. Internal observation using X-ray radiography revealed voids within the weld, and internal observation using X-ray CT confirmed that the voids are located near the center of the weld (between the two aluminum plates). Additionally, by creating a cross-section of the same sample and combining mechanical polishing with chemical etching, we were able to observe the condition of the weld more clearly. 【Summary】 ■ Internal observation using X-ray radiography - Conducted non-destructive testing and X-ray radiographic observation - Voids were observed within the weld ■ Internal observation using X-ray CT - Conducted non-destructive testing and X-ray CT observation - Confirmed that the voids are located near the center of the weld ■ Cross-sectional observation using optical microscopy and tabletop SEM - Mechanical polishing and chemical etching A cross-section tailored to the sample allows for clearer observation. *For more details, please refer to the PDF document or feel free to contact us.

Introducing a case study on the cross-section preparation of large samples (65mm × 28mm) and the observation of their internal structures!

We present an observation case of a large sample (expansion valve) measuring 65mm × 28mm. This sample uses magnetic materials, and due to distortion in the images during SEM observation, we primarily conducted observations using an optical microscope. From the appearance and X-ray radiographic observation, it was found that there are some areas that are not visible in the X-ray. 【Overview】 ■ Appearance and X-ray radiographic observation ■ Cross-sectional observation using an optical microscope *For more details, please refer to the PDF document or feel free to contact us.

We will introduce an analysis example confirming that the welded area has a large distribution of grain crystals.

As an example of EBSD, we conducted an analysis of the cross-section of an aluminum welding joint from the cross-sectional direction, and we would like to introduce it. For a sample where an aluminum plate was spot-welded to an aluminum case, we prepared a cross-section of the weld and performed EBSD analysis. In the distribution of grain sizes, it was confirmed that the weld area has a larger number of large grains compared to the base material. [Analysis Overview] ■ Visualization of Grain Structure - It can be seen that the shape and size of the grains in the weld area differ from those in the base material. ■ Distribution of Grain Sizes - It is confirmed that the weld area has a greater distribution of large grains compared to the base material. *For more details, please refer to the PDF document or feel free to contact us.

Investigation of the joint condition and joining methods of crimp terminals, as well as the types of materials! Introduction to cross-sectional observation and elemental analysis using SEM/EDX.

I would like to introduce the topic of "Cross-sectional observation of copper terminals and elemental analysis using SEM/EDX." We conducted cross-section preparation of the joint area of a copper crimp terminal fixture for resistance measurement, applied chemical etching to the prepared cross-section, and observed the metal structure before and after etching. As a result, we infer that the detected elements are P (phosphorus), Ag (silver), and Cu (copper), indicating that it is a silver-containing phosphorus copper soldering material. *For more details, please refer to the PDF document or feel free to contact us.*

We will introduce an example of analysis using EBSD for screws (Cu2Zn).

The EBSD method allows us to confirm the distribution of crystal sizes and the orientation of crystal orientations. In this case, it was found that there is a significant orientation difference in the valleys of the screw, suggesting that there is a high level of residual stress. Additionally, it was observed that small crystal grains are distributed on the surface of the screw. [Summary] ■ Analysis Method - Observation of crystal structure using EBSD ■ Results - It was found that there is a significant orientation difference in the valleys of the screw. - It is inferred that there is a high level of residual stress. - It was also observed that small crystal grains are distributed on the surface of the screw. *For more details, please refer to the PDF document or feel free to contact us.

[To the owners of parking lots and parking lot construction companies] "I am worried about the possibility of colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those particularly facing sidewalks or roadways are expected to pose risks of dangerous incidents such as pedestrian collisions and vehicle-to-vehicle accidents. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures at various sites and alerts the surrounding area with LED lights and buzzers. The system consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *When using the exit warning system, we kindly ask that you arrange for the switching power supply (24V), LED rotating light, control panel, circuit breaker, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. [Contents Included] ○ Exit Warning System Configuration ○ Comparison Table of Exit Warning Sensors ○ Four Modes ○ Wide Range of Applications ○ Customer Feedback ○ Appearance Diagram / Specifications ◎ For more details, please contact us or download the catalog.
