研究目的
Investigating the effects of electroless Co–Ni–P coating on grain-oriented electrical steel to improve power loss and magnetostriction properties.
研究成果
The electroless Co–Ni–P coating significantly improves the power loss and magnetostriction properties of grain-oriented electrical steel, with a reduction in power loss by 9%–11%. The coating's magnetic nature and reduced thickness also improve the stacking factor in transformers.
研究不足
The study focuses on the effects of Co–Ni–P coating on grain-oriented electrical steel under specific conditions. The scalability and cost-effectiveness of the coating process for industrial applications are not fully explored.
1：Experimental Design and Method Selection:
Electroless plating of Co–Ni–P was applied to grain-oriented electrical steel substrates to study its effects on power loss and magnetostriction.
2：Sample Selection and Data Sources:
Grain-oriented (Fe-3%Si) samples were used, with specific total loss measured using a single strip tester.
3：List of Experimental Equipment and Materials:
Environmental scanning electron microscopy (ESEM), X-ray diffraction (XRD), magnetic property measurement system (MPMS), Talysurf surface profilometer.
4：Experimental Procedures and Operational Workflow:
Samples were coated with Co–Ni–P using electroless plating, with varying pH and coating times to study effects on magnetic properties and surface roughness.
5：Data Analysis Methods:
Power loss, magnetostriction, and surface roughness were measured and analyzed to determine the coating's effectiveness.
