Introduction

Alan George Leatham, an accomplished inventor based in Swansea, GB, has made significant contributions in the field of materials science. With a robust portfolio of seven patents, Leatham has engaged in groundbreaking research, focusing on silicon alloys and metal spray deposits, particularly valuable in electronic packaging.

Latest Patents

Among his latest innovations, Leatham introduced a method for producing silicon alloys that contain over 50 wt. % silicon, often incorporating aluminium. This process involves melting the alloy and inert gas atomizing it to create a powder or a spray-formed deposit. Notably, the method yields an engineering material where silicon forms a continuous phase of fine, randomly oriented crystals, making it particularly suitable for electronic packaging materials. A prime example represents an alloy composed of 70 wt. % silicon and 30 wt. % aluminium, which offers machinability and enhanced application in various electronic components.

Another remarkable patent is for the production of metal spray deposits. This method generates a spray of gas atomized molten metal or alloy directed at a rotating substrate. By carefully controlling the extraction of heat during deposition, Leatham's technique significantly minimizes base porosity and improves the quality of the deposits produced. The innovation of oscillating the spray relative to the substrate further enhances performance, leading to thicker deposits with reduced intensity of reciprocation lines.
