Abstract | This tungsten carbide powder has tungsten carbide as the main component thereof and also contains chromium, wherein, when the mass concentrations of the tungsten and the chromium are measured at 100 or more analysis points selected at random from a field of view in which the tungsten carbide powder is observed by SEM, the standard deviation σ of the distribution in the ratio of the concentration of the chromium to the total concentration of the tungsten and the chromium, expressed as a percentage, is 0.5 or less.
Cette poudre de carbure de tungstène a du carbure de tungstène en tant que composant principal de celle-ci et contient également du chrome, lorsque les concentrations massiques du tungstène et du chrome sont mesurées à 100 points d'analyse ou plus sélectionnés au hasard à partir d'un champ de vision dans lequel la poudre de carbure de tungstène est observée par MEB, l'écart-type σ de la distribution dans le rapport de la concentration du chrome à la concentration totale du tungstène et du chrome, exprimé en pourcentage, est inférieur ou égal à 0,5.
炭化タングステン粉末は、炭化タングステンを主成分とすると共にクロムを含有する炭化タングステン粉末であって、炭化タングステン粉末をSEM観察した視野から無作為に選択した100以上の解析点においてタングステンとクロムの質量濃度を測定したとき、タングステンとクロムの合計濃度に対するクロム濃度の割合を百分率で表したときの分布の標準偏差σが0.5以下である。 |
