Ti-6Al-4V Nitriding via EDM with SiC Powder: Surface Properties

A research dataset by Roberta Nunes Nery dos Santos details the nitriding of Ti-6Al-4V alloy using electrical discharge machining with SiC abrasive powder. The dataset likely contains measurements from surface characterization techniques including optical microscopy, X-ray diffraction, SEM, Vickers microhardness, and surface roughness. Results indicate the formation of a high-hardness TiN layer with an average thickness of 104µm, a 52% increase in surface hardness, and a 31% reduction in roughness compared to the base process.

Use Cases

• Predict surface hardness improvements based on EDM process parameters mentioned in the description.
• Model the relationship between abrasive powder addition and resulting surface roughness reduction.
• Analyze the formation and thickness of nitride layers on titanium alloys from experimental conditions.
• Compare the efficacy of different surface treatment methods for wear resistance enhancement in Ti-6Al-4V.

Strengths

• The description provides specific quantitative results, including a 52% increase in surface hardness and a 31% reduction in roughness.
• The dataset is derived from multiple characterization methods (optical microscopy, XRD, SEM, microhardness, roughness), suggesting a multi-faceted analysis.
• The experimental setup and materials (graphite electrode, SiC powder of 600 mesh, aqueous dielectric fluid) are clearly described.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset's availability, file formats, and sample data are unspecified.
