Feb 15,2011 the tribological behaviour of precipitation#0183;Precipitation is any type of water that forms in the Earth's atmosphere and then drops onto the surface of the Earth.Water vapor,droplets of water suspended in the air,builds up in the Earth's atmosphere.Water vapor in the atmosphere is visible as clouds and fog.Water vapor collects with other materials,such as dust,in clouds.Precipitation condenses,or forms,around these tiny pieces of Tribological properties of magnetite precipitate from Apr 01,2013 the tribological behaviour of precipitation#0183;The experimental results indicate the two types of precipitation structure exhibit quite different tribological behaviours.The free particles in the globular structure could contribute to be a lubricant and consequently resist wear,whereas the compact particles in the lamellar structure may favour an adhesive wear.Tribological behaviour of AFNOR grade Z6 NCT DV 25Tribological behaviour of AFNOR grade Z6 NCT DV 25-15 precipitation hardening austenitic stainless steel with NiCr-B coating in high temperature liquid sodium H.Kumar1,V.Ramakrishnan2,S.K.Albert1,C.Meikandamurthy2,S.Chandramouli2,V.Rajan Babu3,R.Vijayashree3 A.K.Bhaduri1 1Materials Development and Technology Group,
