Analysis of the cold compaction behaviour of TiH2-316L nanocomposite powder blend using compaction models

Author: Machio, Christopher N ; Machaka, Ronald ; Shabalala, T ; Chikwanda, HK Date: Jul 2015 The paper captures the effect of structure and the applicability of compaction models using the cold compaction of a TiH2-SS316L composite powder prepared by high energy mechanical milling. The composite blend was cold pressed uniaxially to ... Read more
Binder Development for Metal Injection Moulding: A CSIR Perspective

Author: Machaka, Ronald ; Seerane, M ; Chikwanda, HK Date: May 2014 The paper reviews the CSIR’s progress and challenges concerning the development of a wax-based binder system suitable for metal injection moulding (MIM). It reports on a consolidation study wherein different widely used wax-based feedstock ... Read more
Determination of optimum thermal debinding and sintering process parameters using Taguchi Method

Author: Seerane, M ; Chikwanda, H ; Machaka, Ronald Date: Jul 2015 Debinding involves long and delicate processing periods of removing binder components from a green body after injection moulding; failure to completely remove the binder components results in distortion, cracking, blisters and contamination ...

Investigation of the powder loading of gas-atomized Ti6Al4V powder using an ‘in-house’ binder for metal injection moulding

Author: Seerane, MN ; Chikwanda, HK ; Focke, W ; Machaka, Ronald Date: Oct 2013 Powder loading is one of the most critical factors in metal injection moulding (MIM) technology. It largely determines the success or failure of the subsequent MIM processes. A gas-atomized Ti6Al4V powder was investigated to determine an ... Read more
Microstructure and tensile properties of heattreated Ti-Mo alloys

Author: Raganya, Mampai L ; Moshokoa, Thabiseng ; Machaka, Ronald ; Obadele, B ; Makhatha, M Date: Dec 2022 Current research is focused on development of ß-type titanium alloys for biomedical applications as substitutes of the undesirable Ti6Al4V alloy. Ti6Al4V alloy has a higher elastic modulus (110 GPa) than that of the human bone (10-30 GPa) and ... Read more
A study of solvent debinding variables on Ti6Al4V green bodies

Author: Seerane, M ; Chikwanda, H ; Focke, W ; Machaka, Ronald Date: Oct 2014 Debinding is one of the most critical and time consuming stage in metal injection moulding (MIM). German and Bose (1997) reported that early debinding practice relied on thermal binder degradation, requiring up to 300 hours for complete binder ... Read more
