Analyzing the optimum contact angles of water droplets to mitigate the e-field stress on polymer insulator

Antony, AD; Arachchi, BATNKB; Gunasinghe, JB; Gunawardana, M; Samarasinghe, R [Conference-Full-text]

The water droplets present in the insulator surfaces cause variation in the e-field along the insulator surface. Variation in the e-field can lead to flashover and accelerate the ageing of the insulator and ultimately will ...
Development of a method to measure contact angles of sessile droplets to analyze and enhance the surface wettability of nichrome

Kumarasiri, AAAP; Amarasinghe, DAS; Attygalle, D [Conference-Abstract]

Nichrome (Ni/Cr) alloys are used in many industrial applications due to their better electrical properties and commercial availability. It is a known fact that these alloys are having a surface passivation layer of chromium ...
Effects of current density on the solder wettability of nickel electrodeposited ni20cr alloy

Kumarasiri, A; Herath, HS; Amarasinghe, DAS; Attygalle, D [Conference-Full-text]

Nickel-chromium alloys are in high demand in the electrical industry, as they have some favorable electrical properties. The formation of a thin chromium oxide layer on the alloy surface protects the alloy from further ...
Lead free solder compatibility improvement on nichrome alloy through contact angle modification

Kumarasiri, A; Attygalle, D; Amarasinghe, DAS [Conference-Abstract]

Nichrome (Ni/Cr) alloys which are used in many industrial applications are known to have a surface passivation layer of chromium oxide (𝐂𝐫𝟐𝐎𝟑 ). This layer alters the surface tension and thereby decreases the surface ...
