Light intensity can affect the polymerization of resin-based material therefore it will also affect surface hardness. To compensate reduction of light intensity becaused of the input of low voltage (200 and 210 volt), the exposure time was prolonged to ...

The effects of material combination and surface roughness in lubricated silicon nitride/steel rolling contact fatigue [PDF]
Four kinds of commercially finished 12.7 min HIPed silicon nitride bearing balls with surface roughness values R-a ranging from 0.002 to 0.016 mum were tested using a four-ball rolling configuration.

Enhanced thermal stability and fracture toughness of TiAlN coatings by Cr, Nb and V-alloying [PDF]
The effect of metal alloying on mechanical properties including hardness and fracture toughness were investigated in three alloys, Ti~0.33Al0.50(Me)~0.17N (Me¿=¿Cr, Nb and V), and compared to Ti0.50Al0.50N, in the as-deposited state and after annealing ...

Mechanical characterisation of water-jet shot peened H13 tool steel surface
A wear-resistant surface is achievable via the surface treatment of various sources such as laser, water-jet, ion beam, and plasma. This paper investigates the parameters of water-jet shot-peened H13 tool steel for minimum surface roughness and maximum ...

Weed control on hard surfaces in The Netherlands
AbstractThe non‐agricultural use of pesticides in The Netherlands declined in the period 1986–2001 from 127 000 to 40 000 kg AI per annum. However use on pavements rose from 23% to 50% of the total non‐agricultural use. To diminish the dependency on herbicides, both preventive and curative non‐chemical weed control methods have been examined.
