Below is a list of events that are coming up. There may be the chance to schedule additional speakers and/or events during the year as we are informed of opportunities. The technical committee is always grateful to members for comments or suggestions as to what the membership would like to see arranged. Please inform us of any overseas visitors that may be candidates to speak to our members.

ACA would like to invite SCANZ Members and guests are invited to attend the first technical meeting in Wellington for 2019.

This will follow a brief ACANZ AGM meeting attended by members of the ACANZ Branch committee.

Callaghan Innovation, 69 Gracefield Road, Lower Hutt

Meet for refreshments from 5.30pm. Presentations start at 6.00 pm.

Corrosion behaviour of materials made by powder-based methods – fishhooks and opportunities

Dr Patricia Shaw, Team Leader Simulation, Analysis and Testing

Dr Karl Dahm, Team Leader

In recent years powder-based manufacturing techniques, such as additive manufacturing and metal injection moulding, have emerged which offer unparalleled design opportunities for parts and components. Such parts, however, may have very different microstructures to those of traditionally manufactured parts. The emphasis to date has been predominantly on mechanical properties but corrosion resistance is highly surface sensitive and therefore may also differ from what the designer may be expecting. In this talk, corrosion investigations of stainless steels and titanium alloys made by a number of traditional and emerging processes will be summarised. Particular emphasis will be given on just how different the same alloy can behave when manufactured in different ways.

Karl Dahm received his BE and PhD (in materials engineering) from Auckland University followed by 10 years in the UK. His research activities focussed on surface-dominated phenomena including surface engineering (coatings especially), corrosion and wear. After 20 years in academia Karl joined Callaghan Innovation in 2015 to lead a team of scientists and engineers researching engineering uses of powder metallurgy and ceramics processing.

Note that the main gate closes at 6pm so visitors will not be able to enter the site after that time. It is therefore essential that attendees RSVP by COB on Monday 18th March, both for catering purposes and so entry onto site can be arranged.
