Cementace a kalen\u00ed<\/p>\n

Case hardening process: carbon is diffused into the surface at 880\u2013930\u00b0C over 4\u201320 hours to a depth of 0.3\u20132.0 mm, then the gear is quenched to form martensite in the case only. The result is a hard case (58\u201363 HRC) over a tough core (30\u201340 HRC). This combination gives the best combination of wear resistance and impact resistance \u2014 the hardened surface resists abrasive and adhesive wear, and the tough core absorbs shock loading at the tooth root. For worm gear applications in automotive, off-highway, and agricultural equipment where shock loads are regular, carburizing is the standard specification. The grain structure improvement from the carburizing cycle also slightly improves the material’s fatigue strength, extending service life beyond what a simple hardness comparison would predict.<\/p>\n<\/div>\n
