Key Characteristics of PM and casting process Cobalt Based Alloy jonalloy tube / pipe withCobalt Based Alloy cobalt stellite metal powder
-
Particle Size and Distribution: The size and uniformity of particles significantly influence flowability, packing density, and the final product’s mechanical and physical properties. Finer powders generally offer a larger surface area, which is beneficial for reactions and sintering but may also increase aggregation.
-
Composition: Metal powders can be elemental (pure metal) or alloyed, combining two or more metals to achieve desired properties such as enhanced strength, corrosion resistance, or electrical conductivity.
-
Shape: Particle shapes range from spherical to irregular or flake-like. Spherical powders provide better flowability and packing, while flake-shaped powders are suited for coatings and electronic applications due to their unique orientation and surface area.
-
Purity: Depending on the application, metal powders can be highly purified to remove impurities, critical for uses in electronics, aerospace, and medical devices where contamination could compromise performance.

Parameters of PM and casting process Cobalt Based Alloy jonalloy tube / pipe withCobalt Based Alloy cobalt stellite metal powder
The casting process of Cobalt-Based Alloy (Jonalloy) tubes or pipes, specifically using Cobalt-Stellite (Co-Fe-W-Ta-Ni) metal powders, involves several critical parameters to ensure high-quality and accurate components. Here are some key parameters involved:
1. **Metal Powders**:
– Particle Size: Fine and uniform particle size is crucial for better flowability, mixing, and packing density during casting. Commonly, the range is between 45-75 microns.
– Purity: High purity of Cobalt-Stellite alloy ensures minimal impurities that can affect the final properties of the cast product.
– Shape: Spherical or irregular shape is preferred for better handling and homogenous melting.
2. **Melting Process**:
– Furnace Type: Induction or vacuum furnaces are commonly used for melting Cobalt-Based Alloys due to their ability to maintain precise temperature control.
– Temperature Control: Accurate temperature control is essential, typically around 1350-1500°C (2462-2822°F), to avoid excessive oxidation or carbide formation.
– Holding Time: Adequate holding time allows for proper homogenization of the alloy before pouring.
3. **Pouring**:
– Pouring Temperature: The alloy should be poured at its liquidus temperature to minimize porosity and ensure proper filling of the mold.
– Casting Speed: A controlled pouring speed helps prevent entrainment of air bubbles and improves surface finish.
4. **Molding**:
– Mold Design: High-quality molds with smooth surfaces and proper draft angles are necessary for dimensional accuracy and surface finish.
– Cooling Rate: Rapid cooling minimizes thermal stresses and promotes grain refinement, which affects strength and toughness.
5. **Post-Casting Treatment**:
– Annealing: To relieve internal stresses and improve mechanical properties, post-casting annealing may be performed at specific temperatures and holding times.
– Heat Treatment: Hardening and tempering cycles can be applied to achieve desired hardness and ductility.
6. **Inspection**:
– Dimensional Control: Precise measurement and control of dimensions using techniques like coordinate measuring machines (CMMs) are vital.
– Microstructure Analysis: Microstructural examination through techniques like Optical Microscopy or Electron Microscopy to confirm the alloy’s phase distribution and grain structure.
7. **Surface Finish**:
– Polishing and Machining: Final surface finish can be achieved through various mechanical or chemical processes, depending on the application requirements.
By optimizing these parameters, the casting process for Cobalt-Based Alloy Jonalloy tubes or pipes can result in high-performance components with desired mechanical properties and surface integrity.
