    Example sentencesExamples
    • Not only can a high-power microwave oven be used to cook food, it can be harnessed for joining, carburizing, sintering, brazing, nitriding, and annealing metal parts.
    • In the original cooling or through subsequent heat treatment, a matrix can be internally decarbonized or carburized by depositing graphite on existing sites or by dissolving carbon from them.
    • That is, the hardenability of the case is significantly greater when nitrogen is added by carbonitriding than when the same steel is only carburized.
    • Micro-sections of structural steels carburised for not less than 8 hours at 925°C and slowly cooled to show cementite networks are photographed at a magnification of 100.

Derivatives

  • carburization

  • noun kɑːbjʊrʌɪˈzeɪʃ(ə)nkɑːbərʌɪˈzeɪʃ(ə)nˌkɑrb(j)əˌraɪˈzeɪʃ(ə)n
    • To make inner layer ferromagnetic, more carburisation and hence longer period of service exposure is needed.
      Example sentencesExamples
      • Heat treatment is often performed in controlled atmospheres to prevent surface scaling, or less commonly carburisation or decarburisation.
      • These various applications may demand resistance to aqueous corrosion mechanisms, such as general corrosion, localized attack, and SCC, or resistance to elevated temperature oxidation, sulfidation and carburization.
      • Simultaneous or subsequent carburisation leads to an additional increase in the ignition temperature.
      • They can contain 35 to 85% Ni, but invariably contain greater than 15% Cr to form an adherent surface oxide to protect against oxidation and carburization at temperatures up to 1000 to 1200°C in air.

Origin

Mid 19th century: from French carbure 'carbide' + -ize.
