Effect of TiAlN Coating on Zinc Melting Recovery of Waste Coated Cemented Carbides AITranslate
Abstract AITranslate
To study the influence of TiAlN coating on zinc melting recovery of waste coated cemented carbides,waste TiAlN-coated WC-Co cemented carbide was recycled by zinc melting at 880 ℃. The failure of the TiAIN coating during zinc melting recovery was analyzed , and the interaction among Zn,TiAlN coating and the substrate was also discussed as well as the existence form of TiAlN coating in the recycled WC powders. The results demonstrate that because of the barrier effect of the coating, uncoated cemented carbide scrap only needs 6 h insulation to be basically melted and loosened during zinc melting recovery,while TiAlN-coated WC-Co cemented carbide scrap needs 9 h. Dissolution and diffusion are not the main reasons for the failure of coatings. Molten zinc goes into the cemented carbide mainly through cracks to react with Co. The stress caused by the different thermal expansion coefficients of the coating and the substrate is the main reason for the formation and extension of the alloy surface cracks. The coating elements and flaky TiAlN coating are found still in the recycled WC powders based on EDS analysis.
