What are the properties of nitinol metallic powder?
Nitinol Metal Powder
(Niti alloy powder) is a Shape Memory alloy (SMA, for short), an alloy with a memory function. It can eliminate deformation completely at lowered temperatures, and then restore it after heating. The alloy with “memory’ effect is the material that retains its original shape.
Many successful applications of nitinol metallic powder have been made in the aerospace industry. The antenna can be made from memory alloy. Fold the parabolic satellite antenna into the body of the artificial satellite before it is launched. It is only necessary to heat the satellite after the rocket launches to place it in a specific orbit. The “memory function” of the folded antenna allows it to unfold and return to its original parabolic shape.
Shape memory alloys have many applications in aerospace, electronics and machinery, biomedicine, bridge building, automobile industry, and everyday life.
What is the best way to prepare nitinol metallic powder?
The following raw materials are used for the PREP process to produce spherical metal powder of nitinol: NiTi bars.
The steps of preparation for the PREP method for the preparation of spherical Nitinol Metal Powder are: the raw materials must be weighed and proportioned in accordance with the experimental design plan and then poured directly into the cemented carbide tank ball milling for wet grind. The ball milling period is 24 hours. After the ball-milling, the pellets are vacuum-dried, with a drying time of 50 minutes and a temperature of 38deg C. They are then added as an forming agent to the granulation. The powdered material is placed in a single-column press to be compressed, then it is placed in an integrated dewaxing-low-pressure sintering oven for sintering.
After batching and ball milling the NiTi bars, followed by drying, granulation forming, and then sintering was a PREP method that produced spherical NiTi metal powder with excellent mechanical properties. The martensite transformation temperatures decrease with decreasing particle sizes of nitinol metallic powders. Preparation PREP produces spherical metal powders of nitinol, which are improved in terms of hardness, density and bending strength.
