Coat­ing con­fer­ence paints a pos­i­tive pic­ture

DEMM Engineering & Manufacturing - - INDUSTRIAL COATINGS - By Steve Hart

The 2014 Coat­ings & Cor­ro­sions show or­gan­ised by Con­ferenz at­tracted close to 200 peo­ple, and ac­cord­ing to its or­gan­is­ers, speak­ers re­ceived high praise from del­e­gates.

Among those giv­ing pre­sen­ta­tions at the Hamil­ton show was con­sul­tant Mike Board­man of LineTech. He helps survey the 26,000 power py­lons up and down the coun­try as a free­lance con­sul­tant.

He says: “The show was well sup­ported by mem­bers of the Aus­tralasian Cor­ro­sion As­so­ci­a­tion, three past pres­i­dents of the as­so­ci­a­tion pre­sented pa­pers.

“I thought the con­fer­ence was ex­cel­lently run, the other in­ter­est­ing thing was that there was some ‘new blood’ there, so we weren’t all preach­ing to the con­verted.”

Nano-tech­nol­ogy was also cov­ered by Univer­sity of Auck­land pro­fes­sor Wei Gao who de­scribed how mi­cro­scopic changes to the sur­face of metal can make it cor­ro­sion resistant.

“That was one end of the spec­trum, but nano is only one of a num­ber of weapons in the tool­box. I think it’s too early for nano tech­nol­ogy to dis­rupt the cur­rent op­tions,” says Mike.

“The cost of cor­ro­sion is be­tween three and five per cent of GDP (gross do­mes­tic prod­uct) to Western so­ci­ety. Those num­bers have been around for a long time, and a num­ber of us have done stud­ies on the cost of cor­ro­sion to var­i­ous in­dus­try groups. Too many peo­ple think that cor­ro­sion hap­pens and ‘oh well’. But it’s not quite true.”

Also at the show was Duane Bag­u­ley of Perry Met­als, he says the show was a good op­por­tu­nity to get a bet­ter un­der­stand­ing about the dif­fer­ent types of cor­ro­sion pro­tec­tion on the mar­ket.

“From the gal­vanis­ing in­dus­try’s per­spec­tive, it high­lighted the need to ed­u­cate the mar­ket in terms of the ben­e­fit of gal­vanis­ing,” he says.

After Duane com­pleted his pre­sen­ta­tion he got lots of ques­tions that he says es­tab­lished that the art of gal­vanis­ing is not a wellun­der­stood process.

“I think the over­ar­ch­ing thing that came through was that while we all have dif­fer­ent so­lu­tions, at the end of the day what we are try­ing to do is of­fer the best so­lu­tions for the cus­tomer, so their prod­ucts are pro­tected for as long as pos­si­ble,” says Duane.

“We need to make sure that the peo­ple who are do­ing the spec­i­fy­ing have a re­ally good grasp of what they are try­ing to achieve. Peo­ple also need to un­der­stand that there can be some se­ri­ous down­sides if they take short­cuts.”
