硬质合金是脆硬材料。它们的性能由化学组成，特别是粘结剂分数和平均硬质相晶粒尺寸来调节。本文主要研究以碳化钨（WC）为硬质相，钴（Co）为粘结相的硬质合金的磨削加工。以前的工作表明，WC-Co硬质合金规格影响磨削行为。本文主要研究硬质合金规格对砂轮磨损的影响。为此，用钴含量和平均WC粒度不同的硬质合金进行磨削试验。通过热机械载荷的采集和砂轮磨损的研究，得出了硬质合金规格对砂轮磨损行为的影响及磨损机理。
Cemented carbides are brittle-hard materials. Their properties are adjusted by the chemical composition, especially the binder fraction and the average hard phase grain size. This research work focuses on grinding of cemented carbides with tungsten carbide (WC) as hard phase and cobalt (Co) as binder phase material. Previous work showed that the WC-Co cemented carbide specification influences the grinding behavior. This study focuses on the influence of the cemented carbide specification on the grinding wheel wear. For this purpose, grinding tests were carried out with cemented carbides that differ in cobalt content and average WC grain size. Based on the thermo-mechanical load collective and the grinding wheel wear, conclusions were drawn about the influence of the cemented carbide specification on the wear behavior of the grinding wheel and the wear mechanisms.
