Abstract: Laser sintering, vacuum melting and laser cladding technologies were employed to prepare the Cr FeNiAlSi high-entropy alloy and coating, respectively. X-ray diffractometer, laser scanning confocal microscope, scanning electron microscope and energy spectrum scanner were used to characterize and analyze the alloy phase and microstructure. The hardness and wear performance of alloys at room temperature were studied using vickers hardness testers and abrasive wear machines. The results show that laser sintering Cr FeNiAlSi（LS） alloy and vacuum melting Cr FeNiAlSi（VM） alloy are composed of BCC and FCC phases, while the laser cladding Cr FeNiAlSi（LC） coating comprises a single BCC phase. The grains of LS alloy are fine and uniform. The LC coating is mainly composed of cellular crystals, with wide grain boundaries and relatively uniform element distribution. The VM alloy is composed of dendrites and petal-like dendrites. There are an Al-rich phase in the grain and a Cr-rich phase in the grain boundaries. The LC coating has the largest surface hardness of 875.1 HV, and the wear amount per unit area is 8.96 mg·cm^-2. Its surface has the shallowest furrows and the best wear resistance. The surface hardness of LS alloy and VM alloy are 803.3 HV and 820.4 HV, respectively, and the wear amount per unit area is 55.50 mg·cm^-2 and 12.69 mg·cm^-2, respectively.
