1：Experimental Design and Method Selection:

Laser cladding was used to deposit composite coatings on Ti-6Al-4V substrate. The study involved analyzing phases, microstructure, microhardness, and wear resistance using various techniques.

2：Sample Selection and Data Sources:

Ti6Al4V titanium alloy plates (60 mm × 40 mm × 14 mm) were used as substrates. Powder mixture of NiCrBSi, WC, and Y2O3 in weight ratio 78:20:2 was preplaced on the substrate.

3：List of Experimental Equipment and Materials:

Equipment included a fibre laser cladding system (IPG YLS-6000 fibre laser), SEM (FlexSEM 1000), TEM (Tecnai F30), XRD (Shimadzu XRD-7000), microhardness tester (HM-800), wear tester (M-200 block-on-ring, MRH-3W), and balance (TG328B). Materials included Ti-6Al-4V, NiCrBSi powder, WC powder, Y2O3 powder, SiC grit paper, acetone, organic binder, aqua regia (HCl and HNO3), and argon gas.

4：Experimental Procedures and Operational Workflow:

Substrate preparation (abrading and cleaning), powder mixing and preplacement, drying, laser cladding with specific parameters (laser power 1500 W, scanning speed 240 mm/min, gas flow 15 L/min), specimen preparation (cutting, grinding, polishing, etching), microstructure analysis (SEM, TEM, EDS, XRD), microhardness testing, and wear testing.

5：Data Analysis Methods:

XRD for phase identification, SEM and TEM for microstructure observation, EDS for element distribution, microhardness measurements, wear mass loss calculation, and statistical analysis of results.
